Fixing thread scheduling issues on Biostar B550MH for Ghostwire
Walking through Tokyo, I noticed these annoying little hitches, especially when turning the camera quickly. It was barely there but enough to be irritating. I checked my logs and saw the Biostar B550MH was messing up the thread scheduling—some cores were idling in low-power states while others were slammed, causing single-core performance to tank. I tried the Windows High Performance plan, but the scheduling latency was still there; it was clear the BIOS power-saving settings were the real culprit. I went into the BIOS, nuked the Global C-State settings, and set the game process priority to High. In RivaTuner, my minimums climbed from 42 FPS to a steady 68-75 FPS, and the input lag vanished. The only downside was my idle CPU temps jumped by 5℃, which I had to fix by rearranging my case fans. Now it sits at 68-76℃ with a power draw of around 85W. The threads are finally balanced, and the fans are humming along at 1400-1600 RPM.
