Why does my character dodge feel laggy during intense fights?

Sneaking through Teryf Forest, I felt a 8.2ms to 12.5ms frame jitter that broke my immersion. I tried locking VRAM frequency manually, but RTSS showed worse stutter. Then I used GamePP Memory Controller Load Monitor to set priority to Max. GamePP Benchmark Verification confirmed latency dropped to 12-15ns and temps held at 65-68℃. The flow is back, and I finally feel the save point was worth it.
