Input Lag

Input lag is the time between a physical action, such as a mouse click or button press, and the matching change appearing on your display. It is the sum of delays in the controller, the operating system, the game, the graphics pipeline and the monitor.

Why it matters

In fast games and competitive play, tens of milliseconds can affect aim and timing. Input lag is separate from network latency: it exists even in a single-player game offline. Common contributors are low frame rate, V-Sync buffering, wireless controller polling, and TV post-processing modes that process the image before showing it.

Example

A rough budget at 60 FPS:

• Controller or mouse and USB polling: about 1-8 ms
• Game logic and rendering: one to three frames, 17-50 ms
• Display processing and pixel response: 5-30 ms or more on a TV in a non-gaming mode

Raising FPS to 144 and switching the TV to its game mode can cut the total by well over half.

Common mistakes

• Blaming the internet connection for delay that also happens in offline play.
• Leaving V-Sync on without trying a variable refresh option.
• Using a TV's default picture mode instead of its low-latency game mode.
