Why does Crysis Remastered drop frames during large explosions?

During massive explosions, the frame rate plummeted from 80 to 35, making the combat feel choppy. I tried manually locking memory frequency in BIOS, but it caused two memory parity errors during boot, which was discouraging. I used the GamePP Resource Scheduler to set priority to Realtime and bound memory threads to high-performance cores. Frame times converged to 12-16ms per FrameView, latency hit 40-60ms per AIDA64, and memory temperatures stayed at 48-54℃ per HWiNFO.
