Why is SCARLET NEXUS stuttering during large-scale combat scenes?

During the climax of battle, severe frame drops made precise timing impossible. I tried cleaning redundant system files, but only freed 5GB, which barely improved the frame rate—a brief moment of excitement followed by disappointment. I used the GamePP Resource Scheduler to fix the page file size at 16GB and disabled background services. RTSS showed frame times stabilized at 12-18ms, and HWInfo confirmed the drive temperature was 40-46℃, eliminating the 16-45ms fluctuations.
