Why does Unknown 9: Awakening freeze when entering buildings?

I felt totally cheated when exploring mysterious buildings; every time I passed through a door, the screen just froze, killing my stealth rhythm. I tried enabling Windows Game Mode for stability, but loading times actually increased by 2 seconds, which was just confusing. I finally used the GamePP Resource Scheduler to elevate the game process priority to Realtime and optimized core allocation. Frame time dropped from 16-40ms to 12-15ms per RTSS, while VRM temps stayed at 52-58℃ via HWiNFO and CPU load hit 85-95℃ per AIDA64.
