Why do I get frame drops in dense areas of Where Winds Meet?

I felt total despair while galloping through the open world; entering dense buildings caused a bizarre tearing sensation that killed the immersion. I tried manually increasing virtual memory to 48GB in system settings, but it didn't fix the stuttering and actually extended loading times by nearly 3s per AIDA64, which was infuriating. I then used the GamePP Resource Scheduler to force the game's main process priority from Normal to Realtime and locked the core affinity. Frame time fluctuations converged from 15-42ms to 8-12ms per RTSS, while VRM temperatures stayed stable at 65-72℃ per HWiNFO.
