1. Establish a baseline
Restart, use stock clocks, note game and driver versions, and reproduce the issue in the same scene.
Reduce input lag in Counter-Strike 2
Repeatable diagnosis before random config edits.
2. Work the likely causes
Use exclusive fullscreen when supported, confirm refresh rate, avoid unstable frame generation, cap below the VRR ceiling and test low-latency options one at a time.
3. Change one variable
Retest after each change. Preserve screenshots of settings and revert changes that do not help.
4. Escalate with evidence
Use official support with crash logs, exact hardware, temperatures, patch version and reproduction steps.
