Why does Black Myth: Wukong stutter during ultimate moves?

Facing strong enemies, the screen would micro-stutter whenever I used a big move, which is lethal during a parry. I tried setting the fan to 'Silent' in the BIOS, but the temperature shot up to 94℃ per AIDA64 and triggered throttling, which made me panic. I used the GamePP Fan Curve Configuration Panel to drop the trigger threshold to 65℃, shorten the response delay from 6-9s to 1s, and add 3℃ hysteresis. RivaTuner showed frame times stabilized at 14-18ms, and HWMonitor confirmed a steady 68-74℃.
