How to fix micro-stutters in The Last of Us Part II on PC?

I felt totally ripped out of the experience while traversing abandoned city streets; the screen suffered abrupt micro-stutters that killed the mood. I first tried enabling High Performance mode in the drivers, but while FPS increased slightly, the frequency of stutters actually worsened. I then used the GamePP Resource Scheduler to elevate the game process priority to Real-time. This stabilized the I/O queue depth, which was spiking to 1024-2048 per AIDA64. Frame generation time converged to 9-12ms per FrameView, and SSD temperatures stayed at 52-62℃ per HWMonitor.
