Why does Dragon's Dogma 2 freeze in bustling towns on RTX 2060?

I felt total despair while exploring Vernworth streets; the screen would suddenly freeze for a full second, completely killing my immersion. I tried setting all textures to Low in-game, but it only bumped my FPS by 5 and didn't stop the stutters because VRAM usage stayed at 95-99% per AIDA64. I then enabled the GamePP Resource Scheduler to set the game process priority from Normal to Realtime. After restricting background services, RTSS showed frame times converging from 35-55ms to 22-28ms, while VRAM temperature stayed at 68-75℃ per GPU-Z.
