Why does Remnant II freeze for 0.3s when switching maps?

I was devastated by sudden 0.3s freezes every time I crossed a Space-Time Gate, which is fatal during fast combat. I tried setting my Windows power plan to High Performance, but my CPU temperature spiked to 92℃ per AIDA64, causing a total system reboot. To solve this, I used the GamePP Resource Scheduler to elevate the game process priority to Real-time. After the change, scheduling latency converged to 85-92ns per HWInfo64, and CPU temps stabilized at 68-74℃ per AIDA64. Frame times dropped from 12.1-25.4ms to 7.2-11.5ms via RTSS, finally making the game feel smooth.
