How to stop micro-stutters in Black Myth: Wukong forest combat?

Fighting bosses with massive particle effects, the CPU load maxes out, and the screen begins to stutter without warning. I tried enabling a low-power mode in-game, but the stuttering remained and input lag increased, which felt ironic and helpless. Via the GamePP Fan Curve Configuration Panel, I locked the pump at 3000 RPM and set the radiator fans to 100% at 80℃. 1% Low FPS improved from 35 to 52 per RTSS, CPU temperature stabilized at 76-82℃ per AIDA64, and Vcore voltage was tuned to 1.15V via HWInfo monitoring to ensure a stable export.
