Why does Nioh 2 stutter during intense combat with Corsair RAM?

I was losing my mind during demon horde battles; micro-stutters kept ruining my precise parries. I tried clearing system temporary files to free up space, but the frame drops didn't improve at all. I finally used the GamePP Resource Scheduler to set the game process priority to Realtime and switched to a High Performance power plan. RTSS monitoring showed frame times converged from 12-35ms to 8-11ms, while HWiNFO kept memory temperatures at 48-54℃ and AIDA64 showed bandwidth fluctuations narrowed to 45-52GB/s.
