Why is Crimson Desert stuttering in high-density battlefield scenes?

Fighting in the vast desert battlefield, my CPU load would spike instantly, causing maddening micro-stutters that made me very anxious. I tried disabling some environmental lighting effects in-game; while FPS increased by 4, the core temperature remained high per AIDA64, a superficial fix that felt defeating. I used the GamePP Fan Curve Configuration Panel to set a 65°C trigger and forced 100% fan speed at 85°C. RTSS monitoring showed frame times converged from 22-48ms to 14-19ms, and AIDA64 confirmed CPU temperature stabilized at 72-78°C with 1400-1600RPM.
