Input Lag Chain Deep: Where Delay Builds Up (Click to Photon)
Input lag builds up across multiple stages: input device timing, game processing, render queue, and display processing. If you fix the wrong stage, you feel nothing — and assume it’s placebo. Fix order matters.
The Chain (Simple)
- Device timing: polling, wireless stability, OS routing.
- Game timing: simulation + frame pacing.
- Render queue: buffered frames add delay.
- Display: processing latency if wrong mode is active.
Practical Fix Order
- Enable Game Mode / low latency mode (remove hidden display delay).
- Stabilize frame pacing (consistent frametimes).
- Reduce render queue where possible (avoid excessive buffering).
- Then tune device layer (polling, wired vs wireless stability).
Rule: do not chase one setting. Find the stage that adds the most delay and fix that first.
