How to fix CPU scheduling stutters on ASRock H310CM-ITX/ac?
When managing my large farm, every time I panned over dense crop areas, the FPS would bounce between 45 and 60, which felt really choppy. The ASRock H310CM-ITX/ac has a very basic power delivery system, causing the CPU clock to flutter between 3.1GHz and 3.6GHz with terrible single-core distribution. I tried turning on 'Game Mode' in Windows, but that surface-level tweak was useless for such old hardware. I ended up going into Advanced Power Options, setting the minimum processor state to 99%, and used a third-party tool to lock the core residency in the high-performance range. In RTSS, the frame time variance dropped from 12-25ms down to a stable 14-17ms. I noticed my idle temps jumped from 35℃ to 48℃ after the lock, so I had to bump up my case fan thresholds to compensate. Now the CPU runs at 62-68℃ and the motherboard stays around 50-55℃. The stuttering is gone, though the fans are a bit louder now.
