How do I fix high input latency in Death Stranding 2 on X870?

In 1v1 gunfights, I noticed a significant increase in button response latency that made competitive play nearly impossible. I initially tried changing the power connector, but there was no improvement, which was confusing and frustrating. I then used the GamePP Peripheral Driver Conflict Detector to identify a background service occupying GPU resources and disabled it. The 12V voltage stabilized at 11.95V-12.05V per OCCT, and input latency dropped below 8ms via LatencyMon.
