Why do Silent Hill 2 effects freeze during combat?

Activating superpowers caused momentary freezes. Lowering quality was unacceptable. I used GamePP Shader Compilation Queue Manager to clear the 4.5GB cache. This forced recompilation. After a second preload to fix startup lag, HWiNFO showed core frequency stable at 2450MHz. AIDA64 confirmed temps at 72-75℃. The stutter is gone, and the game runs perfectly.
