Why does Like a Dragon: Ishin! stutter during Kyoto combat?

I felt totally robbed of the immersion during intense duels in Kyoto; the screen would suddenly exhibit micro-stutters that killed the combat impact. I tried increasing the CPU power limit to 200W in BIOS, but temperatures hit 95℃ per AIDA64 and caused a BSOD, proving that was a disaster. I then used the GamePP Fan Curve Configuration panel to set 70℃ as the trigger for rapid speed spikes and locked the max speed at 2200 RPM. Now, frame generation intervals converged to 11-14ms via RTSS, and CPU temps stabilized at 72-78℃ per AIDA64.
