Optimizing CPU scheduling for Kai no Kiseki on B650MT
Whenever I moved quickly through complex city scenes, the frame rate would inexplicably tank from 90 FPS to 40 FPS, which is just anxiety-inducing. The default scheduling on the Biostar B650MT was a mess, pinning the main game thread to one core at 100% while the others just sat there idling. I wasted a few hours increasing my page file to 32GB, which helped loading times slightly but did absolutely nothing for the micro-stutters—it was a total band-aid solution. I eventually used a process manager to force the game's main thread onto the high-performance cores and disabled several C-states in the BIOS to stop the cores from parking. Monitoring with RTSS, the frame time spikes of 16-55ms flattened out to a consistent 12-18ms. I actually crashed the whole system once by over-allocating threads, but after locking it to cores 0-7, it became rock solid. CPU temps are now 65-72℃ and VRM is around 52-58℃. The game finally feels responsive, and the controls are snappy again.
