Story Used Claude to fix Oblivion Remastered performance

• Upvotes

I've been playing Oblivion since 2006 and was naturally very excited when the Remastered version got shadow-dropped last year. Imagine my disappointment when even after upgrading from 2070 Super to 9070 XT the game continued to run poorly, with low fps and stuttering on my 5800X CPU and 32GB DDR4 RAM.

From various user reports and the fact that even at a low resolution and graphic settings the game was still laggy (e.g. 20-30 FPS in Cheydinhal) it was clear that the problem is in poor optimization. But it was not clear what to do about this, that is, until I've got Claude subscription a few weeks ago.

On the last day before weekly reset of my $20 plan I've had some tokens to burn and decided for fun to launch the game, alt-tab to Claude and ask Opus 5.5 how come the fps is so low. Imagine my shock as it was able to somehow (no reverse-engineering software installed, just asked me to link my GitHub account to Epic organization for access to UE source codes) analyze what's going on and find a few huge inefficiencies. Apparently, the game was reconstructing the whole lighting of a scene in each frame even when nothing was changing, which was obviously a huge strain on CPU that had to parse all this work on a single thread (!).

What followed was an immediate upgrade to the Max x5 plan (btw that gave me an immediate full reset) and two weeks of intense work where we've:

  • Built a benchmark harness so Claude can optimize bottleneck scenarios autonomously while I'm at work, including completely silent and headless mode in case I work from home PC
  • Found ~40 improvements that brought in-city FPS from ~30 to stable 60, open-world average FPS improvement by ~30-40%, and made traversal stutter almost unnoticeable
  • Provided full-support for latest AMD FSR FrameGen, including setting optimizations to avoid stutters and game sending camera information required for full functionality
  • Fixed several bugs in the original game and Remastered code
  • Shared the work on GitHub in a clear, reproducible way
  • Recorded a few demonstration videos to show improvements, Claude was in charge of routing, camera work, music selection and timings.

Work pattern was as follows:

  • Find an in-game place / scenario where I observe poor performance / stuttering. Ask Claude to build a benchmark out of it for independent optimization.
  • Early in the day set /goal to orchestrate work on fixing the identified scenario performance. Limiting it to 2 Opus 5.5 sub-agents was usually enough to not run into 5 hour limit. Computer keeps running at home and I can check progress and steer via mobile app.
  • In the evening review work, test, provide feedback. Usually the topic was resolved, I kept playing until finding a new scenario where performance was bad.

After roughly 2.5 weeks of Max x5 allowance we were able to reach the result you see on the video.

Amazing, for someone who is not even an IT developer, to be able to do something that a multi-billion corporation didn't manage in ~1.5 years since the release.

And I think even the most AI-skeptical people would find it hard to object when AI is used to make existing well-beloved games perform better and have fewer bugs.

If you are curious to review work or try yourself, would be happy to hear your thoughts: https://github.com/LTSharpe/OblivionRemasteredPerformanceFix

Question Am I the only gamer that still prefers membrane keyboards ?

0 Upvotes

Just like the title says, i still prefer membrane keyboards, why ? Because they provide enough resistance to avoid misclicks while still not needing much of a force, and because they don't produce sound (yes i hate the sound keyboards make and also they're annoying for my family)

Edit: i want some suggestions for switches that are silent and low resistance

Build/Battlestation ASUS ROG Astral 5090 | RMA Positive Experience

Thumbnail
gallery
1 Upvotes

Long story short:
I recently purchased an open-box excellent condition Astral 5090 OC from Best Buy. Upon receiving, I took all precautions necessary to verify the GPU, and its hardware which thankfully everything checks out.

I took it to a computer store where they ran furmark stress tests and noticed the 2 outter side fans do not turn on. All variables were taken into account from checking both bios (performance and quiet) modes, to checking all settings on ASUS GPU Tweak III.
From testing on a test bench to testing at home on a Minisforum Deg2, 1000w connected to a Z13 Flow 2025 and still the same result, aside from the performance decrease due to thunderbolt connectivity.

Under load during Furmark via test bench, the temps reached between 70c-75c and the two outter fans never turned on. Post score on 1080p was 30003 (499 fps).

———————-

Resolution:
ASUS technicians confirmed that my two side fans were defective and those fans were replaced.
My 5090 Astral now functions properly, and passed both Furmark and 3Dmark stress tests that ASUS performed on it. ASUS has provided me my shipping tracking information and my GPU will be returned to me soon.

In conclusion, thank you ASUS for repairing my 5090 Astral. The experience I had was exceptional and I can’t be anymore thankful. Despite the stories i read online that made me concerned, I am happy to share the positive ASUS RMA outcome.

Timeline:
Friday, October 2: Received my 5090 Astral open box excellent condition from Best Buy

Friday, October 2: Unboxed shipment at Best Buy to verify that the GPU was in the box and in tact

Saturday, October 3: Took the 5090 Astral to be professionally inspected and tested to verify its functionality, VRAM & ROPS. It was then discovered that the fans were inoperable and everything was documented.

Sunday, October 4: Went to Best Buy to inquire about RMA as Asus requires customers who bought from Best Buy go through the retailer for initiating the RMA. The manager and rep had no idea of that policy but confirmed it through ASUS’s website when they entered my serial number. As this was Sunday, nothing could be initiated under the next business day.

Monday, October 5: I contacted ASUS directly instead of going back to Best Buy to see if they’ll help me despite what their automated RMA system directs me to do with the retailer. On my first attempt, I got through to an ASUS representative fairly quickly. The rep happily stated he would initiate my RMA and began documenting all the details I provided. After 15-20 minutes, I had my RMA reference number and instructions to wait for the next steps of returning.

Friday, October 9: I securely packaged my GPU following ASUS’s guidelines. It was advised not to send any original boxes as they would not be returned back to me. I wrapped the GPU in an anti static bag, with a lot of bubble wrap around it. Placed it in a box I layered with more bubble wrap. Secured it with tamper seal tape all around it. Then placed it into another larger box with more bubble wrap and tamper seal tape. The package was then dropped off at Fedex.

Tuesday, October 13: ASUS confirmed via email of receiving my GPU and it was currently undergoing diagnostic testing.

Thursday, October 15: ASUS informed via email that my package is ready and awaiting courier pick up. As my RMA tracking has not been accessible likely due to the Best Buy automated flagging of purchase. So I called and the rep confirmed it was repaired due to the defective fans and is now being returned to me soon.

Saturday, October 17: My 5090 Astral was delivered to my house. ASUS boxed it perfectly and securely with a foam fitting insert around the GPU along with it being wrapped in a static bag. The package was double boxed with extra bubble wrap. My GPU is in the same like-new condition as it was when I sent it to ASUS. I tested the GPU and all fans work properly.

Discussion 8GB VRAM enough for 1440p?

2 Upvotes

building a new PC under €2000 and putting most of my budget into a top-tier CPU since I mostly play CPU-heavy games. Because of that, I'm intentionally saving on the GPU side for now, hoping to upgrade to an RTX 6000 series card down the line when they come out.

Right now I'm leaning towards a 5060 Ti 8GB . I play a lot of competitive games like Valorant, CS, and Siege, heavily modded Minecraft with shaders, and some AAA titles on the side. I prefer Nvidia sadly and alternative options like the RX 9070 GRE cost around €300 more here, which I'd rather avoid spending (or to a 5070).

For AAA games at 1440p, I have zero issues using DLSS or upscaling, I'm completely fine dropping settings to High instead of Ultra, and I don't care about maxing out Ray Tracing or using heavy texture packs (5060ti is not enough powerfull for that anyway). Given these conditions, is 8GB VRAM really going to be a problem at 1440p, or will High settings + DLSS keep VRAM usage low enough to smooth things out?

EDIT : well boys 5070 it is then

News/Article The "coop-anything" repo, a 'reverse engineer anything' like repo that lets you make ANY existing game co-op. I have already succeeded in deus ex, zelda: ocarina of time, stalker games, dungeon keeper, and fallout NV is WIP but close.

133 Upvotes

https://github.com/cranebeaker/coop-anything

I have been busy adding FULLY functional co op to the CLASSICS of our childhood. I've made a co-op-anything repo, in the style of the REA one that is for making ANY game co-op.

So far I have completed: Deus Ex (fully support online co-op), Dungeon Keeper, Stalker SOC. Currently wip is: Ocarina of Time (very close to 100% synced) and Fallout NV (is WIP - goodsprings quests are fully tested and working so far and the rest is done but needs QA tested)

There are two paths essentially:

  1. Finish what exists. It first researches and will help map out any half-done mods, then dig up their bug reports by scraping discord and forums etc, fixes them, and has automated tests for it with bots and scripts running real game clients to automate much of the QA testing.
  2. Build it from zero. Most games run on a handful of engines (Unreal, Unity, Source, id Tech, Bethesda's Creation Engine) that modders have already mapped out. It can re use information known about that engine, and reverse engineer the rest using tools like REA and Ghidra, then it builds co-op the way mods like Skyrim Together and sm64coopdx did.

Discussion why do people buy single tower air coolers?

0 Upvotes

the reason why im asking this is because dual towers from thermalright are like usually around 30-35 usd/euros (pearless assassin 120 + phantom spirit 120)
and sometimes the pearless assassin even goes for 26 euros! (on amazon)
so why even buy a single tower cooler? genuine question
dual towers do perform significantly better than single towers and the PA120/PS120 are both like a few degrees off from noctuas flagship 150+ euro air cooler so what gives? i recently bought a PS120 for 32 euros for my ryzen 5 5500, do i need one? no but why not? my temps are 25-30 degrees lower vs the stock wraith stealth cooler, from mid 80s in cinabench to high 50s now and it was only 32 euros, why not?

I wanna go with a 2 tb nvme + 1 tb cause it’s actually cheaper and enough for me than going with a 4 tb, what do you recommend going with one drive or two, my idea is to have one for the system and drivers, the other for games and media, is it a great idea or there is something i need to learn before choosing, also for backup if something goes the other way with the windows or something.

Discussion Let’s talk about the RTX 5050

Post image
0 Upvotes

Normal retail price where I got it from was 300$. MSRP for this card is around 249$ the last I checked. So I saved about 20$, which is good in my books. From testing this card it’s pretty decent for its class trading blows with the more expensive 4060. I get around 160FPS in Fortnite and in Forza Horizon 6 I can get around 170 to 180 FPS with DLSS. Marvel Rivals I can get around 110 FPS on average with small dips into the 90s in heavy scenes.

While yes you can find some better cards for a similar price, if you find it for a good price then it’s worth it.

What are your thoughts on this card? Do you think it’s good for its class? Let me know in the comments.

Hello! So I built a pc a while back and its been amazing one of the things I got was a AIO now it was a NZXT kraken elite 360m 2024

Lately my pc been having trouble come to find out after being able to get it to boot is that the pump rpm is sitting at 0

Ive only had it since April it was cooling a ryzen 5 7600x which is a high wattage, high temp cpu paired with a good GPU etc

Im able to get a replacement since im within my 1 year with best buy

But I was looking online and there's some people saying they have problems and some saying they dont, is this just unlucky me getting a bad one or are they genuinely this bad now bc ik nzxt aio used to be pretty good and reliable, other question i got is having a push pull setting with a case like the h9 elite overkill ?

Question To fully shut down daily or not to fully shut down daily: That is the question...

0 Upvotes

Gonna make a very dumb question here but want to get people's opinions on it since I hear mixed responses. Should, in your opinion, a gaming PC be fully shut down EVERY single time you're done using it for that day? Reason I ask is because I just got a new pre-built (yes, I'm aware that is heresy) and have done just that the past couple of days: Turn it on in the morning, put it to sleep mode when I'm away from it, and when I'm done using it would shut it off for the night so it wasn't in sleep while I was sleeping myself.

But then again, I've heard multiple different responses as to whether it should fully be shut down in the way I've been doing it. Consensus said every 1-2 weeks to do that instead and, for my case where I use my PC daily, just use sleep mode. My PC draws little power so I'm not worried about that standby energy use. Just don't want to accidentally be causing more damage than good by turning it off and on again so many times.

Question Upgrading from i5-10400F + GTX 1660 Ti to i5-14400F + RTX 3060 — how big is the FPS jump?

0 Upvotes

I'm upgrading my gaming PC and wanted to hear from people who've made a similar upgrade, especially in Esports games like Valorant and Fortnite.

Old PC:

  • CPU: i5-10400F
  • GPU: GTX 1660 Ti 6GB
  • RAM: 16GB (2x8GB) Crucial DDR4-2667

New PC:

  • CPU: i5-14400F
  • GPU: RTX 3060 12GB
  • RAM: 16GB (2x8GB) Corsair Vengeance DDR4-3600

I play at 1080p on a 240Hz monitor, mainly Valorant on competitive low settings and Fortnite on Performance Mode.

I'm wondering:

  1. How big of an FPS improvement should I realistically expect in both games?
  2. What average FPS and 1% lows should I expect?
  3. Will I be able to maintain a stable 240 FPS, especially during fights?
  4. Has anyone made a similar upgrade? What were your before-and-after FPS numbers?

I'm mainly looking for real-world experiences rather than FPS calculator estimates. Thanks!

There is a great mod on the Nexus called "Path Tracing and Ray Tracing Optimization (Remastered)" that can give you a very nice FPS boost while keeping the same or most of the visual quality.

Anyway I have made a quick install guide and some performance testing of the mod, so If anyone playing TW3 Remastered with PT on and doesnt know about this mod, I really recommend it.

My Specs:
GPU: GAINWARD GeForce RTX 5080 Python III 16GB
CPU: AMD Ryzen 7 7800x3D
RAM: G.SKILL 32GB DDR5 6000Mhz CL30
