Fan Uses AI to Fix Oblivion Remastered PC Performance
The Elder Scrolls IV: Oblivion Remastered was excellent when it came out, bringing the beloved RPG to the modern era, but just like many other games running on Unreal 5, it was a technical mess. However, a fan has used Claude to create a performance mod that improves the game's performance.
An Elder Scrolls IV: Oblivion Remastered fan has utilized Claude to craft a performance-enhancing mod, addressing the technical issues plaguing the game. Released in April 2025, the game was already notorious for its performance woes, which persisted even after patch 1.2 in June 2025. Despite improvements, significant frame rate drops and stuttering remained a persistent issue.
This led to a community effort to address the problem. Reddit user LTSharp showcased a side-by-side comparison of the unpatched and patched versions, demonstrating a marked reduction in hitches. The root of the problem lay in the game's continuous reconstruction of lighting for each frame, placing an undue strain on the CPU. To tackle this, LTSharp employed Claude Opus 5.5, instructing it to pinpoint the issues.
Following two weeks of meticulous work, multiple patches were developed. The most substantial improvement came from distributing processing tasks across more CPU cores, resulting in a noticeable rise in CPU utilization – from a meager 35-40% to a more robust 50-60%. With these enhancements, the game's performance has seen an overall boost, offering a smoother experience to players.
This endeavor showcases the potential of AI in software development, even for those without formal technical backgrounds.
