Reduce Input Lag Checklist v2: Fast Fixes That Actually Move the Needle
Most input lag ‘fixes’ are placebo because they ignore the chain. This checklist targets the links that actually change feel: display mode, timing stability, and background load.
Fast Checklist (In Order)
- Enable Game Mode on the correct input and disable motion smoothing while testing.
- Verify correct refresh rate and resolution are active end-to-end.
- Cap FPS for stable frame pacing (avoid bouncing).
- Kill background load (updates, overlays, recording, sync).
- Test wired input first to isolate wireless issues.
- Only then tune VRR/HDR comfort settings.
Two Red Flags
- Feel changes day-to-day: background load or unstable pacing.
- Feel changes mid-match: spikes, queueing, or device switching.
Rule: do not tune aim until input lag is stable. Otherwise you tune symptoms.
