How to stop Delta Force CPU downclocking on MSI B760M BOMBER DDR4?

I got headshot instantly during an Azmir street fight due to microsecond pauses. Manual frequency locking failed, triggering thermal protection at 78-82°C. I used the GamePP Resource Scheduler to set Real-time priority and High Performance mode. Cinebench R23 showed the score stabilizing at 21000, with core frequency holding at 4.6-4.7GHz instead of dropping to 3.2GHz.
