THE CRUNCH

A modder known as LTSharpe has released a performance fix for The Elder Scrolls IV: Oblivion Remastered, a game notorious for hitching and stuttering, and says it was built largely with Anthropic's Claude AI agent. The mod is a binary code modification, so it changes no game assets or visuals, yet it lifts performance by as much as 68% in the worst case, according to Tom's Hardware. Thankful posts on NexusMods describe the gains as dramatic, with one user saying the overworld stuttering is completely gone.

The work was more than an engine.ini tweak recycled from the original game. Working without source code, since neither the Gamebryo original nor the Unreal Engine remaster is open source, LTSharpe and Claude reverse-engineered the game and built a repeatable benchmarking framework. That let them systematically diagnose the causes of the poor performance, which stems mainly from bad hardware utilisation, and test fixes against the game's real behaviour with modified machine code.

According to LTSharpe, over two weeks Claude diagnosed and fixed bugs in the remaster's Unreal Engine code, the underlying Gamebryo engine, AMD's frame generation code and even the Unreal Engine itself, improving performance and avoiding crashes. Some fixes keep AMD's FSR upscaling and frame generation working despite a long-standing bug that disables them when you Alt+Tab out of the game.

There is a caveat: the tweaks were created with LTSharpe's own system in mind, a Ryzen 7 5800X with a Radeon graphics card, so they may not work as well for everyone. He is inviting other gamers to try the fix and report back, and is already helping with support requests on NexusMods.
