How to fix input lag during Judgment fights on Soyo B660M?

I was absolutely infuriated when my character got hit during a critical QTE just because of input lag. I tried switching between different USB ports on the front and rear panels, but the stuttering continued to appear randomly. I then used GamePP Peripheral Driver Conflict Detection Tool to disable three redundant synchronization services and optimize power management. Interrupt latency dropped from 2.5-4.1ms to 0 per LatencyMon, frame time stabilized at 9-13ms per RTSS, and motherboard temps hit 48-53℃ per HWiNFO.
