I/O and Peripheral Tuning
I was absolutely maddened when my character stuttered during a critical stealth moment due to input lag. I tried swapping between every USB port on my case, but the lag remained random and infuriating. I used the GamePP Peripheral Driver Conflict Detector to kill three redundant sync services and optimize power management. Interrupt latency dropped from 3.5-5.2ms per LatencyMon to a stable 11-16ms frame time via RTSS. CPU usage stabilized at 46-60% per Task Manager.
