Why do I get micro-stutters when dashing in Phantom Blade Zero?

Every time my character flashed forward in battle, an anxiety-inducing micro-stutter occurred, which is lethal during parries. I tried increasing virtual memory to 32GB, but the frequency of frame drops actually increased, leaving me panicked. I used the GamePP Resource Scheduler to set the game's I/O priority to Realtime and disabled background indexing. Frame time dropped from 20-40ms to 14-18ms per RTSS, and memory temps stabilized at 38-42℃ per GamePP while I/O response hit 110-150ms via CrystalDiskMark.
