Fix Input Lag Fast (PC & Console): The No-Placebo Checklist
Most input lag ‘fixes’ are placebo because they don’t target the real delay links. This checklist is the fast path: remove hidden display latency, stabilize pacing, reduce buffering, then kill background spikes. If you do this, feel improves fast.
The Checklist (In Order)
- Display: enable Game Mode on the correct input + correct refresh rate.
- Pacing: apply a holdable frame cap for stable frametimes.
- Buffering: reduce render queue growth (avoid runaway buffering).
- Spikes: disable background sync/scans/overlays during play.
- Online: test latency under load and fix queueing/bufferbloat if needed.
What Not to Waste Time On (Yet)
- Random graphics toggles without triage.
- Daily sensitivity changes while pacing is unstable.
- Buying new gear before testing under load.
Rule: fix the chain, not the symptoms. One broken link ruins the whole feel.
