Why does Resident Evil Village drop frames on Intel Core i5 12400F?

I can't stand this scheduling; despite having a 12th gen CPU, frame drops were severe during large-scale enemy rendering. I first tried the Windows High Performance power plan, but it didn't improve scheduling and only raised CPU temperature by 8℃, which was infuriating. I then used the GamePP Resource Scheduler to set the game's main process priority to Realtime. AIDA64 verified core response latency dropped to 7-9ms, core latency hit 8-10ms via GamePP tool, and temps were 62-68℃ per HWMonitor.
