Why do I get frame drops when rotating the camera in Shadow Land?

Exploring the forests of the Shadow Land, every fast camera rotation caused a noticeable frame drop, which was maddening. I tried increasing virtual memory to 64GB, but the frequency of frame drops actually increased. I used the GamePP Resource Scheduler to set the process priority to Highest and enabled memory write optimization. Frame time converged to 13-18ms per RTSS, memory temps hit 48-56℃ per AIDA64, and fan speed stabilized at 1400-1600RPM per Hardware Monitor.
