How to fix power management stutters in Spider-Man 2?
Swinging through Manhattan was a mess; the visuals would just hitch violently during high-speed movement. Checking the logs, the CPU core voltage on the Colorful BATTLE-AX B450M-T M.2 V14 was jumping between 1.1V and 1.2V, forcing the clock to bounce between 3.6GHz and 4.2GHz. I tried the 'High Performance' power plan in Windows, but the CPU spiked to 92℃ and triggered a brutal thermal throttle. Talk about a fail. I went into the BIOS, disabled PBO, and manually locked all cores at 3.8GHz while cranking the fan curve to aggressive. Using RTSS, I saw the frame times tighten from a wild 16-42ms range down to a smooth 13-17ms. I did have two random restarts at first, but a tiny SoC voltage bump to 1.1V fixed it. CPU stayed between 75-82℃ and VRMs hit 65-72℃. Frame time analysis confirms the drops are gone, and the power scheduling is finally sorted.
