Oblivion Remastered performance problems analysed with Claude
Claude analysed why Oblivion Remastered ran poorly on a fast PC, found wasteful per-frame lighting work, and then helped with two weeks of optimisation work.

The full story
The poster found Oblivion Remastered ran with low frame rates and stuttering (20-30 FPS in Cheydinhal) even after a GPU upgrade, on a 5800X CPU with 32GB RAM. They asked Claude Opus to explain the low FPS while the game was running, giving it access to the Unreal Engine source via their GitHub account.
Claude reportedly found that the game rebuilt the whole lighting of a scene every frame even when nothing changed, which loaded a single CPU thread. Two weeks of work followed, including a benchmark harness so Claude could optimise bottleneck scenarios on its own. The post text available here is cut off before the final results, so the outcome is unverified.
