Controller input lag
Input lag is the delay between pressing a button and seeing it happen on screen. The controller is only one part of that delay. Your connection, PC or console, game and screen all add to it.
What the tester can show you
The tester shows a report rate, how often the browser receives a new update from the controller while you move a stick. A higher and steadier number means fresher input.
Browsers usually check controllers once per screen refresh, so on a 60 Hz screen the tester can't show more than about 60 Hz, even if the controller sends updates faster. Use the report rate to compare connections on the same screen, not as the controller's true maximum. A browser can't measure total button-to-screen lag.
Quick comparisons you can do
- Test the same controller wired, then on Bluetooth. If the Bluetooth number is lower or jumps around, wired will feel more responsive.
- Move further from the PC on Bluetooth. If the rate drops or stutters, you're at the edge of the range or getting interference.
How to reduce lag
- Use a cable. Wired is usually the lowest and most consistent option.
- On wireless, keep a clear line. Stay close to the PC or receiver, and keep USB 3 devices, Wi-Fi routers and metal objects away from the Bluetooth adapter.
- Use the right receiver. On PC, the Xbox Wireless Adapter is often steadier than a laptop's built-in Bluetooth for Xbox controllers.
- Turn on Game Mode on your TV. TV picture processing is often the biggest single source of lag.
- Check game settings. Options like V-Sync and frame limiters can add delay. Some games offer a low-latency mode.
- Update the controller. Firmware updates sometimes improve wireless performance.
