Why does Gray Zone feel choppy during fast turns with 64GB RAM?

While infiltrating enemy camps, I noticed the game felt choppy during fast turns despite high FPS, which totally broke my immersion. I tried enabling Extreme Performance mode in BIOS, but it didn't stop the spikes and caused CPU temperatures to soar to 92℃ per GamePP. I finally used the GamePP Resource Scheduler to set the game priority to Realtime and locked the process to physical P-cores. RTSS showed the frame time curve smoothed out, stabilizing from 11-48ms down to 13-16ms, while GamePP monitored a steady 54-60℃.
