How to fix CPU frequency jumping in Titanfall on Galax B760M Light D4?

I was excited for the high-speed combat, but the frequency scheduling was a nightmare, with the CPU jumping between 3.4GHz and 4.7GHz per GamePP Sensor. I tried disabling C-State in BIOS, but idle temperatures jumped to 62℃ per AIDA64 and the drops persisted, which was a disappointing fix. I used the GamePP Power Plan Switcher to lock the system into High Performance mode and set the game to High priority. Frame intervals converged to 10-14ms per GamePP Analyzer, with CPU temperatures stable at 68-75℃ per AIDA64.
