How to stop FPS dropping from 144 to 60 in Overwatch 2 combat?

During intense team fights, my FPS dropped from 144 to 60 per RTSS, which severely degraded my aiming experience. I tried the Windows 'Ultimate Performance' plan, but CPU temps hit 94℃ per HWMonitor, causing severe thermal throttling. I then used the GamePP Resource Scheduler to lock the game's CPU affinity to high-performance P-Cores and set priority to High. Cinebench R23 showed a 7% response boost, and RTSS confirmed frames stabilized between 120-144 FPS. I can finally compete.
