Why does SCARLET NEXUS stutter during high-speed attacks?

I felt totally cheated when high-speed displacement attacks caused the screen to jump violently, ruining the combat flow. I tried enabling Windows Game Mode, but my frame rates still fluctuated between 48-72 FPS per RTSS, which didn't touch the root cause. I then used the GamePP Resource Scheduler to force the game's main process priority to the Realtime level. After this, frame generation time dropped to 11-14ms per FrameView, and memory temperature stabilized at 42-48℃ per HWMonitor, while memory controller load hit 62-68% via AIDA64.
