The Elder Scrolls IV: Oblivion Remastered has struggled with CPU bottlenecks, inconsistent frame rates and frame times, not to mention traversal stuttering since launch, especially on NVIDIA GPUs. However, one particularly dedicated fan has apparently managed to address many of these issues with the help of Anthropic's Claude AI, achieving some rather impressive performance improvements without compromising the game's visual fidelity.

Reddit user LTSharpe recently shared his experience, explaining how even upgrading from a GeForce RTX 2070 SUPER to a Radeon RX 9070 XT failed to resolve the game's performance problems on his Ryzen 7 5800X system. Frustrated by the situation, he turned to Claude Opus 5.5, which reportedly identified several fundamental inefficiencies within the game's code.

What followed was roughly two and a half weeks of AI-assisted reverse engineering, profiling, and optimization. Despite having no professional software development background, LTSharpe directed Claude through the process, ultimately producing approximately 40 engine-level optimizations packaged into an open-source mod called Oblivion Remastered Performance Fix.
