Fan uses Claude to fix Oblivion Remastered PC performance

A Reddit user known as LTSharp spent two weeks building a mod for The Elder Scrolls IV: Oblivion Remastered that cuts stutters from 66 to 11 in a side-by-side test clip. Created with Claude Opus 5.5, the patch spreads work across more CPU cores and is published on GitHub.

• Stutters dropped from 66 to 11 in the test clip
• CPU utilization rose from 35–40% to 50–60% with two extra worker threads
• The mod took two weeks with Claude Opus 5.5 and no development background
• The game's last official patch, 1.2, shipped in June 2025
