Why does Silent Hill 2 stutter during fast turns in Brookhaven Hospital?

I felt totally immersed in Brookhaven Hospital until micro-stutters during fast turns completely broke the atmosphere. It was jarring. I tried disabling Fast Startup in system settings, but it didn't help and actually increased my game boot time by 10 seconds, which was a total waste. I then used GamePP NVMe Queue Depth Configuration to raise the depth from 32 to 64 and forced high-priority read mode. After this, frame generation time converged to 8-11ms per Frame Time Analyzer, and SSD temps stayed at 48-54℃ per GamePP Hardware Sensor, with IOPS peaking at 120k-150k via the same tool.
