Latency Features Explained: Reflex, Anti-Lag, and When They Actually Help

Latency features help only when the baseline is stable. Learn what Reflex/Anti-Lag type features do, when they reduce queue delay, and when they cause instability.

Latency features are not magic. They mainly reduce render queue buildup when you are GPU-limited. If your timing is unstable or you are CPU-limited, you may see no benefit — or worse behavior. Use them after the baseline is correct.

When They Help

  • You are GPU-bound and the render queue builds up.
  • Your frame pacing is stable and you can retest consistently.
  • The game supports the feature properly.

When They Don’t

  • CPU-bound stutter and scheduling spikes dominate.
  • You stack multiple features without a stable cap.
  • Your display mode/refresh is wrong (baseline broken).

Rule: features come last. Fix timing and queue behavior first.
