Is optimizing thread priority the answer to the scheduling lag when entering cities in PUBG on a B760M?

While looting and moving fast, I kept hitting these micro-stutters that are absolutely lethal when you're trying to line up a sniper shot. Monitoring the backend revealed that the Colorful BATTLE-AX B760M was mismanaging cores, with some threads stuck in low-frequency states, causing single-core performance to crater. I tried lowering the global illumination in-game, but that only gained me 3 FPS and didn't stop the dips—it proved the issue was at the scheduling level, not the GPU. I went into system settings, forced the game process to High priority, and enabled the Memory Fast Boot option in the BIOS. RivaTuner showed the minimums climbing from 55 FPS to a stable 82-90 FPS. I had some brief system hangs after the first priority change, but updating the latest chipset drivers cleared that right up. CPU temps are 65-72℃ at 80W. Performance panel shows even thread distribution; the check is done.
