Why does The Last of Us Part I stutter in Boston ruins with ADATA RAM?

Entering the Boston ruins, the sudden load of high-res textures caused weird fluctuations in memory response, breaking the immersion. I tried increasing virtual memory to 64GB, but instead of fixing the drops, the game froze for ten seconds during map transitions, which was incredibly frustrating. I used the GamePP Resource Scheduler to elevate the game's process priority from Normal to High and restricted background apps. Frame times stabilized at 14-18ms per RTSS, while memory controller load hit 72-88% via AIDA64, and temps stayed at 48-55℃ per HWInfo.
