How to fix 0.5s frame freezes in Helldivers 2 on Z790-P?

Facing swarms of bugs, the screen would freeze for 0.5 seconds without warning, which is fatal in the heat of battle. I tried setting Windows power plan to High Performance; P-Cores responded faster, but E-Core latency remained severe, which felt like a superficial fix. I used the GamePP Resource Scheduler to elevate thread priority to Real-time and locked physics calculations to high-performance cores. RTSS showed frame time stabilized to 11-16ms, with CPU temperature maintained at 75-82℃ per AIDA64 and a 0.01V offset via BIOS.
