Why does Hellblade II freeze during combat with Crucial 8GB RAM?

I felt total despair when exploring the eerie castle; the screen suddenly froze like it was locked, which is fatal during intense combat. I tried disabling all visual effects in Windows settings, but it only freed less than 200MB of RAM, failing to solve the resource scarcity. I then enabled the GamePP Resource Scheduler, set the game process priority to Realtime, and adjusted virtual memory from 32 to 16GB. RTSS monitoring showed frame time converged from 15-85ms to 18-24ms, while HWiNFO64 recorded temps at 42-48℃.
