Why does RDR2 freeze during combat on Jinyue X79 PRO?

I was riding through Saint Denis when the screen started freezing slightly, which is absolutely fatal during fast combat. It totally killed my immersion. I tried forcing all CPU cores to maximum frequency in BIOS, but while average FPS rose by 3, my CPU temperature hit 92℃ per BIOS sensors, causing brutal thermal throttling. I finally used GamePP Resource Scheduler to set the game process to Realtime priority and balanced the audio service. Now, bus load is stabilized at 62-68% per GamePP sensor, and response time dropped to 5.1-6.4ms per HWiNFO.
