Why does MGSV lag during character turns on Manli RTX 5050?

I felt total despair while infiltrating bases; every time I turned, a visible lag spike broke my immersion. I first tried enabling Maximum Performance mode in the drivers, but it didn't stop the stutters and pushed my core temp to 82℃ per HWMonitor. Turns out, I needed the GamePP Resource Scheduler to elevate the game process priority from Normal to Real-time. After this, the frame generation interval converged to 5.3-6.7ms per GamePP sensor, and scheduling fluctuations dropped to 12.4-15.8ms via AIDA64. My temps finally stabilized at 65-71℃ per HWMonitor.
