Fixing RX 7650 GRE driver lag in Kai no Kiseki
The optimization in this game is a complete disaster; walking through the main city would drop my FPS to 25, which honestly made me want to throw my keyboard. The Sapphire RX 7650 GRE has plenty of power, but the driver was hitting severe scheduling delays with complex city models, causing GPU usage to bounce between 40% and 95%. I tried enabling Resizable BAR in the BIOS, but it only added 3 FPS to the average while the lows stayed at 22—a total joke. I finally installed the latest stable driver and forced a full re-compile of all shaders, while switching my power plan to 'Ultimate Performance'. In city tests, my FPS went from 25-40 up to 40-52, with way less variance. I did deal with two Blue Screens of Death (BSOD) right after the update, but disabling a third-party monitoring tool fixed it. The card now runs at 65-72℃, and the fans are locked at 1400-1600 RPM based on my exported profile.
