Why does Resident Evil 9 freeze during monster attacks in corridors?

Exploring those eerie underground corridors was a nightmare when the screen suddenly froze for 0.5s right as a monster attacked. I initially tried lowering texture quality to medium, but the walls became blurry and disappointing, though VRAM usage dropped 1GB per GPU-Z. I then accessed the GamePP Resource Scheduler, raised the game process priority to Realtime, and limited browser GPU usage. VRAM bandwidth utilization converged to 84-86% per GPU-Z, and VRAM temperature stayed at 58-63℃
