[u/frankiewalsh44]

More stutters than actual FPS is insane. Yet when you complain about the stutters, you have a bunch of people ready to bite saying " The game is smooth on mine, Upgrade your PC/there is an issue with your GPU"

[u/LTSharpe → u/frankiewalsh44]

It will still stutter even on very strong PCs because most of the work is on a single thread and it gets overloaded when the game is loading new cells. And the patch fixes this

[u/frankiewalsh44 → u/LTSharpe]

Thanks. its just wild to me how peoole keep putting things like " its very smooth on mine" when the game is just obviously broken. Like we have tech channels like Digtal Foundry who have access to multiple GPUs from lower end to the best of the best, and if it stutters on a freaking 5090/9800x3d then I refuse to believe that it doesn't stutter on their system.

[u/WhatIs115 → u/frankiewalsh44]

" its very smooth on mine"

I think these are the same group of people who cant feel the input lag when turning on FG and then bump it up to 6x.

Edit: some latency numbers straight from the nvidia overlay, since someone mentioned it.

Cyberpunk 2077 155 FPS base 17ms total latency - no FG.

2x FG 207 FPS - 26ms total latency.

4x FG 306 FPS - 31ms total latency.

6x FG 379 FPS - 35ms total latency.

Now imagine how much worse it is when you're starting at 60 FPS where your input latency is already 10ms higher by default at 60 FPS vs 155 FPS and it gets worse from there.

[u/adkenna → u/WhatIs115]

'You mean it's not normal for the game to react a full second after you push the button?'

[u/No_Accountant3232 → u/adkenna]

I remember arguing with someone that a 500ms delay really kills games playability and had someone arguing that it was fine and you get used to it

[u/zgillet → u/No_Accountant3232]

I mean, I got "used to" playing Sniper in Team Fortress Classic over AOL dial-up, where you would press the mouse click and mail the bullet to their head using standard shipping.

I still got crushed by anyone with DSL or *gasp* cable broadband internet, and finally playing in a gaming shop with LAN PCs was like heaven on earth.

[u/Kondinator → u/WhatIs115]

There are sooo many people who play videogames whos' standards are so unfathomably low, so when they say "its smooth on mine" or "plays just fine for me" they mean 25 fps and stuttering, but because the game looks good they dont care.

[u/dookarion → u/Kondinator]

they mean 25 fps and stuttering

[Playstation and Xbox will remember that.]

[u/Burpmeister → u/WhatIs115]

Does 6x exist?? Fucking hell, just the normal 2x is too much lag for me on fps games. 6x must be on par with the og led televisions lol

[u/DubiousBrushwagg → u/WhatIs115]

The same people don't think that the stutter/hitched step every 24-30 steps your character takes is stuttering. They probably think it's an animation bug.

[u/VoidVer → u/WhatIs115]

Same people who buy 5k computer, 3k monitor and leave their refresh rate at 60hz

[u/Fr00stee → u/frankiewalsh44]

legit had several people on this sub argue with me that optimizing new games is impossible for devs because "games are too complicated", it's honestly baffling

[u/PolicyWonka → u/Fr00stee]

Whelp, at least it’s something AI can solve if humans can’t.

[u/gtrash81 → u/Fr00stee]

This.
And even the whole argument "EvErY pC iS dIfFeReNtLy CoNfIgUrEd" is
such nonsense.
Develop and design around a base spec and everything that is faster will run the game faster.
For missing features and stuff the programming languages have a solution:
if/else and case.
Your game needs something?
Check if the hardware can provide it.

[u/No_Accountant3232 → u/gtrash81]

Yeah, games can straight up say no to DLSS if you have an amd card so it's not like that's impossible 

[u/Gangleri_Graybeard → u/frankiewalsh44]

The game was so broken for me. It corrupted my safe file twice. Hours of progress gone because they were not able to fix a bug that already existed in 2006. I'm done with Bethesda slop.

[u/Darg727 → u/Gangleri_Graybeard]

Because it's literally the oblivion engine being run through a custom unreal engine translation. They didn't fix everything because they didn't actually do much to the original engine.

[u/canteen_boy → u/Darg727]

On one hand, I love that I can refer to 20 year old forum posts for help with bugs, but on the other hand it would be nice not to have to.

[u/Tim_Huckleberry1398 → u/frankiewalsh44]

It's really infuriating because most of the time someone with a 5090/9800x3d can just bruteforce poor performance either way. If they're saying its bad they're doing it to help people with lower tier systems. It doesn't run better on a 5070 than a 5090, stop giving shitty companies excuses to release shitty products people.

[u/VexeenBro → u/Tim_Huckleberry1398]

Not exactly. Stuttering issue - especially on UE5 - is a real problem and is very visibly noticeable on 5090 as well. The worst offenders I had are all new Silent Hill games, but other UE5 suffer from it to some degree. I think the only one UE5 game that I really did not met any stutter was ARC Riders.

[u/Diedead666 → u/Tim_Huckleberry1398]

oh, man we do still feel them with them cpus, and have a review channel friend who tried on a lower end cpu/budget minded cpus and he said it made some games feel unplayable. We know if it stutters on ours its very bad UE5 is terrable in that sence. Games should not even have loading in stutters with all the tech out now and how much ram is now "normal" they NEED to optimize as noone can really upgrade anymore with the price of everything.

[u/Zed_or_AFK → u/LTSharpe]

Yeah, patch fixes the engine problems. Unbelievable. This is a shitty era we live in, but some perks we are still getting.

[u/MorningFresh123 → u/frankiewalsh44]

Most people are bad at noticing. In every sphere of life. The worst part is they will treat their misperception as absolute truth and work backwards in interpreting any evidence to the contrary until it fits their preconceived idea. It is emblematic of a much bigger and broader problem.

[u/neverphate → u/MorningFresh123]

Best example of this I can think of happens on the PS5 sub.

An incredibly large amount of people swear that the DualSense controllers don’t have stick drift. They always insist it’s the fault of the user for playing competitive or otherwise “heavy” games, or being violent with the controller when stick drift appears.

In reality a lot of games have good deadzones and so they don’t even notice that they have stick drift. Or they are lucky and it hasn’t developed stick drift yet.

They don’t even accept the possibility that they might be wrong, like zero tolerance for other opinions lol. Bunch of absolute lunatics.

[u/SpartanJAH → u/neverphate]

That's really interesting, as somebody who used the same DS4 for over 1000 hours of intense gameplay and never had issues, meanwhile every dualsense I've owned (4) started having unplayable levels of stick drift in just a couple months. I feel like the only way you could prevent a dualsense from stick drifting is never actually using it. Wild to hear that people act like it's fine.

Edit: also my DS4 that went the distance was from OG ps4 launch, I got a new DS4 closer to PS5 release and that thing felt way cheaper crapped out after a couple months too, so maybe Sony just decided to stop trying some way through the PS4's life.

[u/neverphate → u/SpartanJAH]

The one that came with my PS5 developed severe stick drift in like a year. Second one I bought to play with my wife somehow developed even worse drift in 3 months. DualSenses are just complete shite.

[u/BrawndoOhnaka → u/SpartanJAH]

I'm guessing it's a matter of lack of quality control in production, because my experience is exactly the opposite. I've been using a DS4 that I got second hand with very light use and it has about six years of heavy use now, and it has stick drift that I have to account for. Meanwhile, my DualSense I've used on PC and can see the wiggling in DS4 windows and it doesn't have any noticeable degree of stick drift after about 3 years of heavy use and dropping.

[u/ChurchillianGrooves → u/BrawndoOhnaka]

Crazy thing is the 1st party controllers quality has gone down dramatically while 3rd party has gone up while remaining cheap.

It's not like back in the ps2 days when you kept a garbage madcatz controller around for when multiple friends wanted to play.

8bitdo or gamesir have better longevity than 1st party now.

[u/MrBig0 → u/MorningFresh123]

Dawg, have you ever played Dead Space 3 on PC? There's a bug in that where all of the doors (the ones that you can open with your power thing) make their door opening and closing sound one per rendered frame for the entire time they're rendered on screen. It literally sounds like the apocalypse at all times and it made the game completely unplayable for me. 

But it happens on every single install of the game on any hardware, and TONS of people claim it didn't happen in their copy. And all least two people I personally know reinstalled it to discover they were wrong. 

There's a like 100+ page thread on the EA forums of proof and EA just telling everyone to fuck off and they aren't fixing it ever.

[u/sabin1981 → u/MorningFresh123]

I'm one of those that sees, and deeply reacts to, motion judder on TV. Whenever a camera pans in films or TV shows, I see the judder from 24fps, it never looks smooth or comfortable to me :(

[u/SomeoneNotFamous → u/frankiewalsh44]

I have a 5090 and 9800X3D, the game will stutter no matter what but it's obviously way way better with specs like that.

Game's optimization is quite a joke.

[u/CrimsonBolt33 → u/SomeoneNotFamous]

I know it won't happen...but all these fan mods with AI to improve performance need to be industry standard in studio.

I have been making these too myself for a few games. It's laughably easy.

With AI, there should be VERY few if any games shipping with massive performance issues because AI can diagnose and suggest (and fix) most of them very fast and easy.

Obviously bad coding and deep structural issues in the code can not be so easily fixed, but AI can help there too...

[u/SomeoneNotFamous → u/CrimsonBolt33]

I actually think it will happen, good studios will use AI for the right things.

[u/doneandtired2014 → u/frankiewalsh44]

" The game is smooth on mine, Upgrade your PC/there is an issue with your GPU"

What's funny is that you can set everything to below low, run the game at a crisp 320p on the fastest hardware you can buy, and 1% and .1% frametimes are no different than what they would be if you were pursuing everything to ultra at 4K. That behavior can then be replicated across a myriad of hardware, software, and driver configurations.

That shit cannot be unseen once you notice it and I often wonder if the denialism comes from the fact people don't want to admit they paid full price for crap the developer couldn't be bothered to optimize before it went gold and couldn't be bothered to fix after launch across all versions.

[u/No_Accountant3232 → u/doneandtired2014]

These are the same people that watch 4:3 content stretched because then it takes up the whole screen. You can't convince people their perception is wrong when it's never something they clock should be wrong. they also crank their radios to cover the sound of brakes squealing 

[u/BaconJets → u/frankiewalsh44]

I've never seen the game running smoothly on a machine in my life. People who say otherwise just can't perceive the stutters, and I'm slightly jealous of them.

[u/who-dat-ninja → u/frankiewalsh44]

use this magic ini tweak that changes everything!!!

[u/DarkFantom → u/frankiewalsh44]

Yea, some people I know have a literal perception of 3 on a DND scale (that's hella bad). They can't even notice the difference (so they say) from 30-60 fps and also have issues seeing aoe's on the ground in mmos. 

[u/TruthAffectionate595 → u/DarkFantom]

It is always incredibly surprising to me how people can just deal with having 30 fps. Sometimes my friends will be lagging in game and when I ask if it’s ping or fps lag they cant tell the difference. Like?? Your game is a slideshow man what do you mean you can’t see that

[u/halycon8]

Just tested this for myself alongside Optimax, another mod that claims to improve performance and fix stutters. Be aware ofcourse that this is a sample size of 1, YMMV.

- No mods, max settings, no DLSS/FG for my baseline test. Averaged 42fps during a 1 minute sprint across the open world, with about 6-7 stutters often happening at the same location during repeated tests.

- With this AI mod, my FPS and 1% lows were not affected whatsoever, no gain or loss. However, stutters disappeared almost completely. No stutters in 2/3 runs, a single stutter in one run.

- With Optimax, FPS and 1% lows improved dramatically, about 15-20% with the highest "ultra quality" preset (42fps up to 51). However, absolutely no stutter improvement. Still experienced the same 6-7 stutters as the baseline.

With both mods installed, I got the same FPS boost from Optimax with the stutter free gameplay of this new mod. Happy gamer!

[u/Falkenmond79 → u/halycon8]

I guess this mod online comes into its own when using lower end hardware. A beefy CPU and GPU would have enough resources to spare to „brute force“ the issues OP listed I guess. If it had enough power to spare it shouldn’t be a problem to run things on a single thread, if that one is fast enough. So you won’t see much benefits from parallelizing it. But removing the times the CPU has to wait would reduce the stutters. Interesting. This is just my layman’s guess though.

[u/Markie411 → u/Falkenmond79]

not really honestly, stutters are still there even on my 9800X3D. Though, I did use a tool that pre-compiles shaders for Oblivion Remastered (about 30gb worth of shaders) and that reduced shader comp stutter by a lot, however, the game still has bad traversal stutter. I'm curious to try this mod out

[u/Vladislavej]

I mean, if it is working what is the issue? How is this slop if it actually helps FPS? This is not the same case as the Epic Launcher saga…

[u/SerLarrold → u/Vladislavej]

I think the ideal usage of AI in gaming (because it will be/already is being used in development no matter how much people plug their ears) is for efficiency gains. Optimization is hard, tedious, and less sexy than new features but it’s probably the number one complaint gamers have. If you make reliable tests to ensure things run properly and then run optimization passes with Claude I say why not. That’s making life better for everyone.

Where I don’t wanna see AI is in things like art direction, quest design, narrative stuff, etc. That’s the human element of games that makes them good. Don’t let AI do the artistic job!

[u/Ooze76 → u/SerLarrold]

I think that’s the opinion of most people when it comes to use AI in gaming. It’s just some people for some reason I don’t understand want everything done with AI and shit on devs saying it does a better job. I agree with you by the way.

[u/Tinominor → u/Vladislavej]

because ignorance

[u/AKinkyTurtle → u/Tinominor]

why the fuck are you getting downvoted...

[u/Tinominor → u/AKinkyTurtle]

Its easier to downvote and reject reality than it is to swallow their pride I guess.

[u/superearthjanitor0 → u/Vladislavej]

It isn't a issue, this is great.

[u/FanDowntown9880 → u/Vladislavej]

Calling it AI or vibe coded slop has never been about the actual quality of the software. People call it slop because they dislike AI as a whole and only assume that it must be worse due to being made with AI. But we're now approaching the point where using AI is simply going to bring better results than doing it yourself in 90% of cases, at least when it comes to programming. Hard pill to swallow for a lot of people, including me partly. But theres just no escaping that reality. Better come to accept it

[u/Ok-Interest9727 → u/FanDowntown9880]

even assuming that AI code is as good or better, at some point AI companies will need to start generating profits and will jack up their prices at least 10x

everything we're seeing now is a consequence of AI companies subsidizing 90% of the cost

here's another fun fact: once you let AI agents start adding code to your codebase you become 100% dependent on AI as nobody has time to understand what the agents are doing

oh and as the codebase grows the number of input tokens also grows, not exponentially but way faster than O(n)

[u/silverist → u/Vladislavej]

Given Bethesda, it would be an achievement if it was made to run worse.

[u/-The_Blazer- → u/Vladislavej]

Also, this is like one guy messing about with his personal PC to wrangle a game made by a billion-dollar corporation. Very different expectations.

[u/MorningFresh123]

Off-the-shelf Claude can fix a massive game that one the biggest developers in the world shipped broken and evidently couldn’t find an easy solution to manually and you’ll still have half of Reddit in denial about every game using AI in development. Not to mention that the AI is the worst it will ever be.

[u/GrossM15 → u/MorningFresh123]

I doubt theres loads of peopl that have a problem with an AI assisted backend (if it is checked to be not more buggy than human code). What people dont like is when the UI, assets, sounds, etc are generic slop.

[u/Retroficient → u/GrossM15]

I'd like to say this is the standard consensus world wide. With a very loud minority otherwise

[u/Aeroncastle → u/MorningFresh123]

The dev has to test things AND it has to work, modders don't even have to be able to read that they are putting in the mod and they can promise anything with 0 accountability

[u/Clever_Angel_PL → u/Aeroncastle]

yeah but it seems like in this case human developers didn't take enough time to test either

[u/FellaVentura → u/Aeroncastle]

And they do with for no profit.

[u/Ordinary_Player → u/MorningFresh123]

I wonder if Sony greenlit Bungie unvaulting old Destiny 2 content because Claude and its 4000 concurrently running agents can just do it on its own lmao.

[u/ltsDat1Guy]

Seeing this thread is exactly why I fucking hate redditors. Regardless of how it was made cool fucking patch op.

[u/FrigginRan → u/ltsDat1Guy]

Using AI tools during development is different from “vibe coding” but most redditors are either too stupid or too ignorant to understand the difference. They just like to updoot the “slop” comments.

[u/Worldly-Local-6613 → u/FrigginRan]

Most of them have absolutely no clue how current AI assistant tools even work in a development context and legitimately believe that any moron can just type in a couple of sentences and accomplish these kinds of software implementations.

[u/auctus10 → u/Worldly-Local-6613]

If there's anyone who thinks any development is done without Ai assisted tools in 2026 they are quite delusional.

[u/Ereaser → u/auctus10]

There's still some. Especially when it's about confidential applications. I've moved teams 3 months ago and before I wasn't allowed to use any AI, let alone coding assistants/agents.

[u/Osteoprdoza → u/FrigginRan]

I doesn't help that in my experience, AI assisted software engineering is called vibe coding even in professional settings, or at least at my company.

[u/Skellicious → u/Osteoprdoza]

AI assisted software engineering doesn't exactly roll off the tongue.

[u/Hyper_Mazino → u/FrigginRan]

Ignorant it is.

You still have people who declare DLSS upscaling and Frame Gen as "pure marketing" and AI slop.

Some people can’t be helped.

[u/Responsible_Camp_559 → u/ltsDat1Guy]

For real. The top comment made me cringe so hard. Gamers being gamers, I guess.

[u/Blackpapalink → u/Responsible_Camp_559]

Nah. This is reddit. It's redditors being redditors.

[u/PCBuilderCat → u/ltsDat1Guy]

The complete death of nuance when it comes to any discussions involving AI use on Reddit is so infuriating. Just a bunch of virtue signalling weirdos 

[u/Vyviel]

People like you are my heroes actually using AI for good

[u/Difficult-Cup-4445]

My expectations and standards for Bethesda were low but holy shit. Their entire studio has been outperformed by one guy and a Claude account. Well done you, I might have to buy the game now it's playable.

Absolutely shameful performance from Bethesda.

[u/0Tezorus0 → u/Difficult-Cup-4445]

Just to be the devil's advocate here, virtuos studio mainly developed the remaster.

[u/DrugandAlcoholLover → u/Difficult-Cup-4445]

And yet if Bethesda admitted to using AI even in the most vague way, the entire internet would go apeshit over it

[u/Deathmore80 → u/Difficult-Cup-4445]

Tbf when oblivion remastered was made, the best ai models at the time were complete shit compared to today, and the tooling was in its infancy, none of that agentic stuff and most people were still just using the web interfaces or maybe vscode + copilot or the old cursor at best. It's really improving at an absurd rate. Heck even open source local models that can run on a single gaming GPU massively outperforms anything from before early 2026.

[u/LTSharpe → u/Difficult-Cup-4445]

Would've been cool if they'd give me a small % of all the extra sales this is going to generate. Would've used it to fix their other games

[u/maria_la_guerta → u/Difficult-Cup-4445]

Their entire studio has been outperformed by one guy and a Claude account.

That isn't necessarily true at all. Those devs are building for millions of people across a huge range of hardware. Claude was optimizing for just one machine in this case.

I'm positive that Claude would be able to find some overall improvements here (the game is quite old at this point) but these are always going to be the tradeoffs to accept when you're building software for the masses.

EDIT: the GitHub states it's only been tested on one machine, which kinda proves my point.

[u/Thomasedv]

What were the technical issues found and changed/fixed that helped performance? What kind of bad things did the devs leave in the game that made it slow? 

[u/LTSharpe → u/Thomasedv]

from my post in r/oblivionmods

• Each frame the game was re-building Sun/Moon, forcing it to re-calculate how light falls on each loaded object leading to crazy unnecessary CPU load. This was replaced with updates only in case something changes.
• There were lots of inefficiencies in memory operations, forcing the game to constantly allocate/de-allocate, now minimized via use of buffers
• Lots of operations (for example, preparing DirectX commands for drawing) were on a single thread and have now been parallelized
• Traversal stutter due to the game forcing loading of new cells / npcs inside them / linking objects to the physics engine / unloading old cells is now significantly reduced by allocating work across several frames without changing how the game behaves
• Several bugs leading to crashes, both in the original game code and in Remastered, have now been fixed
• Various Frame Generation improvements, from removing stuttering when CPU was forced to unnecessarily wait, to introducing full support for new AMD FSR Frame Generation (requires installation of AMD FSR dll 3.1.4, instructions in readme), including passing camera info to the algorithm
• Various stutter-reducing measures when opening menus / inventory and after loading screens. Shaders are now pre-loaded before the game starts.

[u/siamkor → u/LTSharpe]

Each frame the game was re-building Sun/Moon, forcing it to re-calculate how light falls on each loaded object leading to crazy unnecessary CPU load. This was replaced with updates only in case something changes.

Holy shit. 🤣

[u/Canamerican726 → u/LTSharpe]

It almost sounds like they didn't bother doing any performance testing and optimization on the game!

[u/Adavanter_MKI → u/Canamerican726]

In fairness... this is kind of what A.I was supposed to do. Humans checking and rechecking their millions of lines of code every time they add something isn't always feasible.

They call it optimizing and developers use to do it quite often, but games keep getting bigger and bigger. So now they sort of just up the requirements to brute force the problem.

Now with A.I... it can just look through the lines of code and note where there's performance hits. It's kind of fantastic it can do this. As all games could become much more optimized. This means getting more out of older hardware and potentially pushing games a bit further as well as it opens up a little leg room.

[u/Chris-346-logo → u/LTSharpe]

Why is there no response to this lol😂

[u/Rudolf1448 → u/Chris-346-logo]

People are still picking up their jaw from the floor

[u/CrazyBird85]

The anti AI are shitting on you in most of the subreddits this is posted. But when looking at the Github I am just simply amazed by how these are simple and seemingly logical modifications that optimise CPU and memory usage. This is the type of optimisation the devs should have done prior release or in a patch. Instead the customers get radio silence since July.

I hope they (Bethesda) pick up on this and review the optimisations that you, or lets be honest Claude is recommending. Combing these recommendation with a review of experienced developers could make it even more stable (because that might be a risk with your approach of using only Claude without any experience as a developer/expert) and part of a future patch.

[u/Funky_Metal_Man → u/CrazyBird85]

Honestly this if anything indicates the utter apathy of that company if what appears to be fairly low hanging fruit of optimization was not even addressed. There is a difference between a studio being unable, and unwilling, to do the legwork to make a more quality product.

[u/Annoyed_Sai → u/CrazyBird85]

Bethesda has already abandoned the game. No proper patch in the last year. Whether AI-assisted or not, only people that have not played Oblivion Remaster can look at this and say "No actually, this is bad cuz ...."

[u/thedybbuk_ → u/Annoyed_Sai]

There were mass layoffs at Virtuous Studios as soon as the game shipped. It looks like Bethesda only contracted them for development and not for post-release maintenance. All that knowledge is gone. And obviously, this Frankenstein experiment of a dual-engine setup was going to need post-release maintenance.

Annoys me no end because obviously a lot of care and attention went into stuff like art design and it's one of my favourite games ever made. It just needed some player feedback and metrics gathered post-release, and it could've been an all-time classic remaster. No amount of playtesting can compete with actual information gathered from millions of players.

[u/Annoyed_Sai → u/thedybbuk_]

What a shame. The fact that they were able to manage this dual-engine remaster shows they had good talent working there. Mass Layoff after shipping such a game is a loss for everyone. I only hope we get ES6 in a working state at launch cuz Bethesda sure as hell isnt going to work on it too much. Other than once-in-a-while useless patch that breaks everything ofc. I do have hope for Skyblivion though. Supposed to release this year.

[u/Past_Canary3806]

To many (simple) people a solution isn’t a solution unless some dude wastes hours of his life doing something the hard way. 

Most of Reddit would ride horses to work if they weren’t caught up in the moral paradox of a subservient animal being their car. 

Use stupidly good tools to improve things (and be transparent about it), and let the haters hate.

[u/LTSharpe → u/Past_Canary3806]

The choice is very simple, either live with the current stuttery mess devs left behind (if they didn't fix in 1.5 years, they are not going to fix it) or use AI to help ourselves. I think the answer is obvious

[u/Apprehensive-Might14 → u/Past_Canary3806]

Reddit acts like programmers were writing perfect code with zero bugs before ai when game development is well known for spaghetti code and being held together with duct tape and paper clips. They would lose their minds would much googling or use of stack overflow of copy and pasting code before ai. They also think it fine for a programmer to waste their limited free time doing tedious work on a game code for free.

[u/mightbebeaux → u/Apprehensive-Might14]

sturgeon’s law. most human output is slop.

[u/plebbut → u/Past_Canary3806]

Most Redditors are complete morons who don't know the first thing about AI, but have strong feelings against it because they can't buy cheap ram.

[u/ContagiousDeathGuard → u/plebbut]

AI and it's consequences are ultimately complicated... It has incredible potential but potentially dangerous ramifications, threatening people's jobs, spreading misinformation (biases, hallucinations) anti social consequences like noise and water pollution, resource drain, and furthering the slow destruction/homogenisation of culture. With that being said, it is still incredible (case in point) and hopefully we can overcome it's downsides.

[u/BloodyGotNoFear → u/ContagiousDeathGuard]

"RAM"ifications you said?

[u/emmabvibing → u/plebbut]

Are those of us who actually work in fields that utilize it and have detailed understandings of how they work allowed to have strong feelings against it, or will we also be written off as morons because you dont like our opinions

[u/somethingrelevant → u/plebbut]

yeah it's crazy people don't like AI because it's making their lives worse

[u/Jdsnut → u/somethingrelevant]

Or that I now have to go through an ai prompt, when I know what document im looking for.

[u/veggiesama → u/plebbut]

That seems like a fine reason to be against something, if it makes your life harder or worse in some way. Oblivion mods aren't worth it.

[u/Immediate_Idea2628 → u/plebbut]

Consumer goods have gone up, but at least the shareholders win?  How does that benefit me?

[u/No_Sheepherder_1855]

Curious to know, how much did it cost to get this running? 

[u/LTSharpe → u/No_Sheepherder_1855]

Like 50 bucks in subscription costs + electricity to keep my PC running for ~16 hours a day running benchmarks and fixes

[u/Chareon → u/LTSharpe]

Too much. Just think about all the shareholder value that would cost these companies.

[u/zetrox01 → u/LTSharpe]

The fact that a random dude with a 50 bucks and claude it's enough to fix that mess to me just prove that they can fix the game, they just don't wanna fix, or even better, nobody in the company try to meet with you to see what you have done to incorporate in the game in a future update patch to make things official, to me just prove the lack interest to fix things

[u/jusalilpanda → u/LTSharpe]

How much person-time (man hours) did you take and how many total AI hours, just the 16? I'm curious as a dev watching the gains AI is giving others.

[u/GalaxLordCZ]

At the end of the day, I don't see a problem with AI use in this case, you're transparent about it, no one else was doing it, so why not?

[u/ToXiiCBULLET]

when a random person with claude can do better than a professional studio you know something is fucked

[u/MatiasPalacios → u/ToXiiCBULLET]

Let's be honest, Claude is better than 90% of the programmers out there.

[u/KiryuBatman → u/MatiasPalacios]

90% is very conservative at this point. And it's only getting better.

[u/zgillet]

This. This right here is what AI should be used for. This would be an absolute INSANE tool if it could be generalized.

Imagine, instead of "compiling shaders", an AI tool could tailor a game's code to your hardware? Heck, a local LLM could do this.

That's the type of stuff I'm on board with. Not the massive techbro/corporate take-over of the planet that is happening.

Imagine source code protection being a thing of the past, and a company has to rely on good customer service instead of simply having the best software and a patent.

But no, that's not what it will be, will it. Greed will not allow AI to be a good thing.

[u/HenryKushinger → u/zgillet]

Nah bro we need deep learning super slop 5 to make all our games look the same, that's way more important than optimization

/uj

[u/Douchieus2 → u/zgillet]

Source code is already a thing of the past. Games are being reverse engineered so fast now it's hard to even keep up.

In the one SINGULAR aspect of AI I do actually welsome our overlord it's that so much progress has been made in the homebrew/jailbreak in the last month it's hard to keep up

I'm seeing shorts of people playing Diablo 2: Resurrected in VR. What a time to be alive.

[u/ObjectivelyLink]

I wonder if they can fix Jedi survivor that’s a good game that’s genuinely ruined by the stutters.

[u/KobeJuanKenobi9]

In every thread like this it becomes clear that the average person doesn’t know what vibe coding actually means

[u/unimportantinfodump → u/KobeJuanKenobi9]

Isn't vibe coding when you just say

Make windows run faster.

And then AI spits out code and you just slap it on and send it

[u/PolarizingKabal]

Game devs really should start getting used to having AI fix and streamline their code. Make games more optimized.

Games as a service would greatly benefit from it IMO.

With the shortage of storage and ram and the years of devs releasing games unoptimized. I think it's time.

I think it would be wild to see AI actually fix bloated games like Destiny and actually help the game run better.

[u/TomasdeVasconcellos]

This is pretty amazing man. If I may ask, what model did you use, is Opus enough or Fable had to pick it up? Is this a matter of asking Claude to optimize a game?
I always wanted to contribute to the community with Claude, but I never really knew how to start.

[u/LTSharpe → u/TomasdeVasconcellos]

Opus 5.5 at XHigh mostly. Will see if Fable 5.5 would help bring stutters to 0

[u/BurdensOfTruth]

Great, now if only someone can make a patch for UE5 itself that you can just slap onto every poorly performing UE5 game to make them less shit.

[u/djwikki]

Y’know, reading through the guy’s process and how he used Claude AI, it’s a use case where I can actually get behind.

The user is a person who knows how to code well. All the code lines they wrote and proofread themself (given it was at the suggestions of the AI). They primarily used Claude to look through and interpret the source code that wasn’t theirs in order to find the problem areas faster.

The ethics of AI aside, the two largest issues with entirely vibecoded projects from inexperienced devs is that 1) AI spits out code with many bad practices that make it extremely hard to maintain and bug fix for anyone, and 2) while the AI is capable of making large projects that work, it is incapable of fixing bugs it created during the process. This leads to a lot of sloppy “as is” projects that a vibecoder is incapable of maintaining.

I have high confidence that this user is able to bug fix the code that they wrote. Therefore I accept the use of AI here.

[u/asclepiannoble]

I love the TES games but Bethesda's work is an embarrassment vs. what modders like this bloke do. Those stutters in vanilla are out of control

[u/kardioid23]

Are you planning on doing this with any other notoriously stuttery games?

[u/LTSharpe → u/kardioid23]

I'm planning to inspire people to fix and improve their favorite games

[u/ThinkedThought]

If this is what an oblivon modder can do, imagine what an aware one can do.

[u/patrick-ruckus]

lol remember when the devs said they optimized the game for the switch 2, and they would carry those changes over to the other platforms?

that was months ago and still silence. but if they finally release that patch then i hope their changes pair well with this mod. 

[u/RHCProy]

So cool! Does this aply to handhelds?

[u/RectumExplorer--]

This is why I'm not against AI in the video game industry. Obviously they don't want to spend money optimizing their shit, but I was always convinced they could have used AI to optimize their code, because modern games do not look good enough to justify their system requirements. Especially UE5, games look 20% better than 2018 titles, yet need 500% better components to run.

[u/StraightAct4340]

Bro shared a news about himself

[u/superearthjanitor0]

Looked at the GitHub and why the fuck couldn't Bethesda do this themselves? What the fuck are they even doing?

[u/PandaParado → u/superearthjanitor0]

From the article:

The developer—or perhaps we should say, coordinator?—is careful to acknowledge that the performance tweaks were created with his system specifically in mind and that they may not work well for others.

This is almost always the case for these kind of 'easy' fixes. Gamers wine that a dev doesn't do something when the reality is they have way bigger stakes and way more things to think about than a modder. I'm a software developer and the first thing I think when I see something like this is 'Ok, does this change break anything else?'. IDK, if this mod does break anything, but there is always a tradeoff.

Not to defend Bethesda, I've been pretty annoyed with them lately like most other. I'm just pointing out that Software is almost never as simple as it seems.

[u/BatBoss → u/PandaParado]

Same thoughts, as a career dev.

Although I do think it's possible he found some real drawback-free performance gains, tbh. When it comes to optimization, you only really have incentive to get it "good enough" to ship. A fan who is willing to invest a bunch of personal time for no pay could very well take it past "good enough".

[u/Falkenmond79 → u/BatBoss]

Read his list of fixes further up. Seems he legitimately found some real performance sinks. That sun/moon thing is wild. I bet you 10 bucks that’s just a legacy thing left over from the old days and a „that’s how we have always done it“ thing. Possibly even creation engine specific though I know this was done in UE5.

[u/BorgDad42 → u/Falkenmond79]

As a SE myself, I may use this as a basis to figure out the Shivering Isles DLC Bossfight crash. I was loving playing the remaster, and then my game kept crashing , and crashing, and it was there in the original game, no fix as far as I know. I haven't picked the game back up since then. Been over a year. 

[u/Yorrins → u/superearthjanitor0]

How can you still ask that in 2026? Bethesda is literally a dogshit company that has no clue what its doing and has been releasing half finished buggy products ever since fucking Arena.

[u/HungryRaven4 → u/superearthjanitor0]

They didn't have Claude in 2006

[u/max1001]

The love/hate relationship this sub has with AI.

[u/LordofDsnuts → u/max1001]

A lot of people hate AI unless/until it's something they like.

[u/FastFooer → u/max1001]

I’m just seeing a AI-bro brigade right now…

[u/KlondikeBoat]

Does this work on the GamePass version?

Also, the SA in the WH said it's SI not AI. Are you the enemy? /s

[u/LTSharpe → u/KlondikeBoat]

Yes, GamePass version included, although I have Steam so couldn't test. Let me know how it goes.

[u/PushDeep9980]

How does it run on steam deck?

[u/Fickle_Side6938]

AI used correctly, nice one

[u/Galentine41]

Awesome work. Do you think it could apply to other unreal engine games?

[u/ArthrogryposisMan]

Can they make fallout new vegas more stable?

[u/bigthog]

It’s surprising how the Reddit hive mind will criticize vibecoded projects even when they offer benefits. Many Redditors seem unaware that vibe coding still demands knowledge and experience to produce a quality product. Just like in any profession, when a tool emerges that simplifies your work, you’d be an idiot not to use it. Great job and I hope more projects like this emerge for other UE5 games to enhance optimization (looking at you stalker 2)

Edit: this post has received a lot of attention and has spurred plenty of good discussion. However, a few people are upset with my definition of vibecoding so I am deeply sorry for those who I have offended. I didn’t think a definition was so serious but to some it is.

[u/GuyentificEnqueery → u/bigthog]

"Vibecoding" is too broad a term. It means anything from "I have an AI tool that autocompletes mundane syntax" to "I asked ChatGPT to spit out a program and did nothing to verify it is safe or works".

[u/D_Ethan_Bones → u/GuyentificEnqueery]

Terminology and labels are always misused, especially in the news.

Elsewhere on Reddit, someone just asked...
>if we have news about curing cancer every week, then why is there still cancer?

Answer: scientists make inflated claims to get grants, then news companies inflate them further to get traffic.

[u/wandering-monster → u/D_Ethan_Bones]

I know it's not your point, but the real answer is to that question is:

Cancer is not one disease, and trials take a long time.

A huge number of incredible treatments have come on the market in the last decade, and have reduced the chance of dying from cancer by something like 70% overall, with numbers closer to 100% survival for certain types caught early enough.

The next generation of immune and personalized therapies will cut that remaining 30% (which are a mix of late detection, rare cancers, or treatment-resistant mutations) by more than half, improve early detection, and reduce side effects dramatically over the next 5-10 years.

[u/Rhowryn → u/bigthog]

Generating code, then using actual expertise to review and debug it, is not vibecoding.

[u/frankiewalsh44 → u/Adrian_Alucard]

If a vibe coded AI on Claude can fix a game and make it playable whilst one of the biggest game devs in the world who have access to any resources can't, then what does that say about the state of game development ? Its funny seeing Claude doing things better than the so called game devs, and then they had the audacity to release a broken game and charge $60 for it.

[u/refinery_eyes → u/frankiewalsh44]

I don't think it says that much about the talent of the devs.

I think it does say that many game publishers, like almost every other company nowadays, do not care about providing you with a decent product and are only interested in cash grabs.

People are optimistic to think AI will change this, whereas I think that when game dev studios really start heavily utilizing AI, they will not use it to create better products, but instead will use it to push out cash grabs faster and faster.

That would follow the pattern that we've seen with AI so far; by and large, people do not use it to make high effort products faster than they otherwise would, but rather to mass produce a lot of low effort products.

[u/Elfyrr → u/frankiewalsh44]

It’s definitely information access (or lack thereof) … many of these companies/devs are competent in different areas but of things tend to be behind patents/methods/structure/IP/etc. These LLMs can be trained on all many different kinds of methodology to bridge the information gap and problem solving.

[u/Corrodiny122 → u/Adrian_Alucard]

Well, thank Claude for this optimization mod then.

[u/Zargabraath → u/Adrian_Alucard]

Reddit’s fanatical hatred of anything to do with AI is so insufferable now

DLSS is AI and it basically doubles performance in games for no real visual downside. Hell the AA from DLSS is way better than the dogshit TAA everyone was using before DLSS took off

Most people don’t actually care what tools are used to make a game, or a mod, they care if it works. And if this mod can work in reducing oblivion’s awful traversal stutter then I am glad we have it

[u/randombulgarian10 → u/Adrian_Alucard]

"computa, fix this game so it performs better, make no mistakes"

That's not how it works man.

[u/TheEmpireOfSun → u/randombulgarian10]

Most blindly AI hating karma farming and virtue signaling trolls think that's how it works.

Can't wait how some people will say "I am not improving my performance because this is AI slop mod". Hopefully devs will start using AI to finally optimize their games better.

[u/Outcast129 → u/TheEmpireOfSun]

I saw a redditor recently comment that he would rather Cancer not be cured if it was AI that was a critical tool in the process of finally finding the cure.

That is how bad the anti-AI brainrot has become on this platform. He really really believed it too.

[u/TheEmpireOfSun → u/Outcast129]

Which is really funny because we are using AI to cure cancer and other diseases for at least 15 as far as I remember, maybe even more. And at the times it was "incredible" and "exciting". These days virtue signaling is more important than actually curing cancer for idiots.

[u/tekprodfx16 → u/Adrian_Alucard]

The changes wouldn’t have taken place without him being involved though so at the very least he is the director of the changes and that makes him at least partial creator 

[u/FyreKZ → u/tekprodfx16]

I'm sure he also did plenty of testing. The mod author acted as a project manager, just not the developer.

[u/INannoI → u/FyreKZ]

people on reddit don't know what a project manager is

[u/iKhAoTiKK → u/INannoI]

These people haven’t worked past minimum wage.

[u/waterbed87 → u/FyreKZ]

Yeah I really hate the narrow mindedness around AI development. Sure some of the tedious hand writing of code itself is less (and the industry is shifting that way to let’s be real and honest with ourselves) but there’s still a lot of human thought, decision making and testing that goes into a quality result. There’s agentic development and there’s Claude make it good and there’s a huge huge difference in results.

[u/chazzeromus → u/FyreKZ]

i've become what many despise

[u/TheeSquanto → u/Adrian_Alucard]

When somebody hits someone else with their car on purpose, do you blame the car or the driver?

If someone shoots someone on purpose, do you blame the gun or the person?

AI wont do this by itself. So yes, this dude's the mod author. The gap between intent and content with development is just being closed in. Either you sit on reddit and say things like "oh AI did this its not even real" or enjoy the benefits of somebody using a controversial yet powerful tool to make something positive.

[u/EnigmaticQuote → u/Adrian_Alucard]

"No the forklift stacked those pallets! You fool you could never lift that!"

[u/sunvsthemoon → u/Adrian_Alucard]

Such a BS answer. Then you do it. Clown response.

Just because it was made with Claude doesn’t mean the author doesn’t have knowledge of the process and how to effectively use tools. It just means a single person was able to do it.

[u/jordanbtucker → u/Adrian_Alucard]

You're not allowed to use any tools to do anything then.

You can't take credit for that photo. The camera did it.

You can't take credit for dinner. The oven did it.

You can't take credit for that math homework. The calculator did it.

You can't take credit for getting to your destination. Google Maps did it.

Anyone who makes this argument doesn't understand how much work goes into steering an AI. And even as it becomes easier, you'll eventually just get used to the creature comforts that come along with it. Just like any other tool.

[u/Spike18 → u/Adrian_Alucard]

I think we're going to enter a point where all/most coding isn't deemed "authored," similar to how we don't call a user using a calculator to solve an equation a mathematician.

[u/TheReviewerWildTake → u/Spike18]

More likely we gonna enter an era where anti-ai cultist noise will just die out, and people who provide solutions for relevant problem will be thanked for providing solutions for relevant problems.
Just like we do it in any other field, without calculating "manual vs machine" ratios.

[u/RedditVIBEChecked → u/Spike18]

I mean, we do call them a mathematician. We never said you weren't a mathematician for using an abacus, nor a slide ruler, nor a calculator, nor a graphic calculator, nor Wolfram Alpha.

Its as to whether or not that the tool is a primary function of your job determines whether or not you are a mathematician. Saying mathematicians don't use calculators is like saying chefs don't use measuring cups.

[u/shox12345 → u/Adrian_Alucard]

And, so what? Did you do the improvement? No? Then shut up, someone did and either use it or shut the hell up.

[u/Majestic-Coat3855]

modders having to optimise Bethesdas games:

[u/tombatron]

Strong work friend!

[u/demoman92]

Still the only game that I regret buying on release and not refunding because I thought "hey, obviously Bethesda will fix this".

[u/DanteMustDieeee]

Why are people complaining about this? AI used to replace humans in making art is bad. I would never support a product using ai to create visuals or come up with a story, but why is using ai to write some code to fix performance a problem? It’s just tedious busywork and no real human art is being affected. No real human vision is being compromised to cut corners with a soulless machine. These are tasks that AI is actually fine for.

[u/Tragilos]

[u/Mr_Gobbles]

This gives me hope for older games that are constrained by their legacy CPU core use limits.

[u/Peryite123]

AI haters are the most bizarre and strange people I’ve met. I was born in the early 90’s and I have never seen so many clowns against a “tool” to speed up work flow ever in my life.

As long as a human is still verifying the final product who fucking cares what “tools” you used along the way.

[u/Grix1s → u/Peryite123]

Nuance is lost nowdays.

I can detest the use of AI as a creative tool for art, videos and music for the ethical concerns it raises, and at the same time I can admit that, as a tool outside of scenarios like the previously mentioned, AI is a ridiculously amazing tool that speeds up all sorts of workflows in incredible ways, from finding issues to creating corrections and organizing it in cohesive and understandable ways.

But no, its either bad or good, it cant be both at once.

AI is here to stay whether we like it or not, what we can hope is that its reined in and regulated.

[u/DangJorts]

This is the sort of thing that AI can be helpful with. I think everyone freaking out is tired of AI slop and shovelware so they paint the tech with the same brush.

[u/aelfwine_widlast]

This is the kind of work AI excels at that humans can’t easily do. It’s the exact opposite of slop, and we should be celebrating a new era for porting and modding.

[u/CelebrationOdd7810]

Can you explain in technical terms what was the problem and how it was fixed?

[u/Slash_DK → u/CelebrationOdd7810]

Honestly just read through https://github.com/LTSharpe/OblivionRemasteredPerformanceFix/blob/main/src/OblivionPerfFix/OblivionPerfFix.ini

No real code there, only feature flags and explanations. A lot of it makes you go Holy Shit!

[u/PCBuilderCat → u/Slash_DK]

Maybe I’m a pessimist but I’m willing to bet the person you replied to has no actual interest in explanation but instead just wanted to ‘gotcha’ OP over their AI coded work. 

Which is stupid when OP couldn’t have been more transparent about how they used AI to create this. 

[u/def_not_jose → u/CelebrationOdd7810]

There were mistakes and Claude made sure there are no mistakes
