Why does my Monster Hunter Wilds frame rate randomly drop from 60 to 30 FPS during critical hunting scenes?

Hunting in Monster Hunter Wilds was anxiety-inducing when my frame rate randomly dropped from 60 to 30 FPS, ruining critical strikes. I tried updating the chipset driver first, but it caused a blue screen restart instead of fixing the stutter. I used the GamePP Peripheral Driver Conflict Detection Tool to identify a conflict between the chipset driver and power management. I reset the driver and switched the power plan from Balanced to High Performance. Frame time converged to a stable 16-18ms range per GamePP Frame Time Analysis, and motherboard temp stayed at 55-60°C via AIDA64, setting a stable baseline.
