Why do I experience micro-stutters in Dead Space Remake corridors?

I was thrilled to max out textures with 16GB VRAM, but I noticed a strange stuttering sensation while walking slowly through corridors. I tried setting the NVIDIA Control Panel to 'Prefer Maximum Performance', but my idle temperature jumped by 15℃, which felt like a waste of energy. I used the GamePP Power Plan Switcher to lock the minimum frequency at 1500MHz during gameplay. Frame times converged to 8-12ms per RTSS, and GPU temperature stabilized at 62-68℃ per GPU-Z. The movement is now buttery smooth.
