Why do I get 100-200ms micro-freezes in The Last of Us Part I?

While exploring Boston ruins, I noticed micro-freezes of 100-200ms whenever entering new areas, which totally broke my immersion. I first tried increasing virtual memory to 64GB, but while crashes decreased, micro-stutters still fluctuated between 15-30ms; it just didn't hit the core issue. I then used the GamePP Resource Scheduler to identify a 12-18ms scheduling delay in the D300 memory controller and set the process priority to 'High'. RTSS monitoring confirmed frame times converged from 22-38ms to 11-15ms, and AIDA64 showed memory temperatures stable at 42-48℃.
