Why does Phantom Blade Zero stutter during rapid turning scenes?

I felt totally ripped off when high-intensity combo battles were ruined by micro-stutters every time I turned quickly. I tried disabling Fast Startup in system settings, but it didn't help and actually increased boot time by 8s, making me doubt my hardware. I then used GamePP NVMe Queue Depth Configuration to raise the depth from 32 to 64 and forced high-priority read mode. Frame generation time converged to 9-12ms via Frame Time Analyzer, and SSD temps stayed at 45-52℃ per AIDA64, with IOPS hitting 110k-140k via GamePP Hardware Sensor.
