Input-to-Pixel Chain: Where Lag Really Comes From
Input lag is the total delay from your action to the visible result. The only reliable way to reduce it is to map the chain and remove the biggest delays first.
The Chain (Simple Version)
- Input device
- System and driver
- Game engine and frame queue
- Rendering and frame pacing
- Display processing and sync
Symptoms That Point to the Right Link
- Feels delayed even in menus: display processing or system buffering.
- Feels inconsistent: frame pacing spikes.
- Feels fine offline but bad online: network jitter and server timing.
For the full step-by-step, use the Reduce Input Lag playbook under Fix.
