About Input Lag Test
Measure controller input lag, latency and polling rate to find delay before it costs you a match.
Input lag is the delay between pressing a button and seeing the result on screen. It adds up from the controller, the wireless connection, the game and the display. A few extra milliseconds can make aiming feel heavy and timing in fighting or rhythm games feel off. An input lag test helps you find which part of the chain is slow.
Where Input Lag Comes From
- Controller: polling rate and Bluetooth vs wired connection.
- Display: image processing, low refresh rate and V-Sync.
- Game: frame rate and engine buffering.
How To Lower Input Lag
Use a wired or 2.4GHz connection when possible, turn on Game mode on TVs, use the highest refresh rate, and keep the controller close to the phone or receiver. Compare results before and after each change so you know what actually helps.
