Why does Nightingale stutter during cross-realm teleportation?

While exploring fantasy dimensions, I noticed slight jumps in the image during fast movement, which totally broke my immersion. I tried clearing the system cache to release pressure, but frame rates still fluctuated between 48-72 FPS per RTSS, leaving me completely confused. I then used the GamePP Process Priority Manager to lock the game process to Realtime priority and disabled redundant network services. After this, the frame generation interval converged to 12-17ms per FrameView, and core temperature stayed at 64-70°C per AIDA64, while GPU-Z showed a steady 2310-2505MHz. It's finally smooth.
