Why does The Mageseeker stutter during intense mid-lane team fights?

I felt a total disconnect in responsiveness during mid-lane team fights; the screen would jump every time I cast a skill, killing my immersion. I first tried disabling unnecessary startup items in Windows settings, but it had zero impact on real-time memory scheduling. I then used the GamePP Resource Scheduler to force the game process priority to Real-time and capped background browser memory. RTSS monitoring showed frame times converged from 12-22ms to a stable 6-9ms, and AIDA64 confirmed memory temps stayed at 42-48℃.
