Ever fired up a remaster hoping for a smooth trip down memory lane, only to be greeted by a stuttering mess? That's been the reality for many Oblivion Remastered players since launch. But one fan decided to fight back with an unusual weapon: AI.
The Elder Scrolls IV: Oblivion Remastered arrived in April 2025 and, despite being a great game, it was plagued with performance issues—something that's become all too common with Unreal 5 titles. More than a year later, those problems persist. The latest Steam patch, 1.2, landed back in June 2025, but significant performance problems remained. So the community took matters into their own hands.
Reddit user LTSharp posted on the ChatGPT subreddit with a video showing the unpatched game running side-by-side with their patched version. While the raw frame rate increase isn't huge, the patch dramatically reduces stutter—going from 66 hitches in the unpatched clip to just 11 in the patched version. That's a massive improvement in smoothness.
In their post, LTSharp explained one of the culprits: "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." They then ran Claude Opus 5.5 alongside Oblivion Remastered, tasked it with identifying the problems, and after two weeks, ended up with a patch.
Crucially, this wasn't just a quick prompt-and-done job. LTSharp describes the process as "two weeks of intense work" with plenty of trial and error. The biggest performance boost seems to come from spreading the work across more CPU cores. In the video, CPU utilization jumps from 35-40% to 50-60%, with around two extra threads engaged. And since the samples were recorded on a rig with a 5800X, there's probably more room for improvement.
AI usage is one of the biggest controversies in gaming right now, but this feels like a decent use of the tech. LTSharp was simply disappointed that after "upgrading from 2070 Super to 9070 XT, the game continued to run poorly, with low fps and stuttering," and decided to use Claude to fix it—despite having no background in software development. Luckily, they've posted their work on GitHub, so others can build on it.
If someone with relatively little experience can reduce stutters this much, imagine what seasoned developers could do with forks of this project. It's a sharp contrast to recent AI controversies, like Epic delaying a Star Wars shooter to implement an "AI-first" policy where no hand-written code is allowed, or an Xbox business analyst ranting that the industry is "pretending" not to use AI. This mod shows AI as a helpful tool, not a replacement.
