Mouse & trackpad

Mouse lag, stutter or delay

The polling rate test above shows how often your mouse reports. A low or unstable reading, or gaps in the trace, point to the connection.

Start with a quick test

1
Move the wireless receiver closer
Use a USB extension cable to bring the receiver within about 30 cm of the mouse, with a clear line of sight.
2
Keep it away from USB 3 ports
USB 3 devices and ports can interfere with 2.4 GHz receivers. Use a USB 2 port or move the receiver away.
3
Charge or replace batteries
Many mice reduce performance when the battery is low.
4
Clean the sensor and use a good surface
Blow dust off the sensor. Glass and glossy surfaces confuse many sensors; a mouse pad helps.
5
Check the polling rate setting
Gaming mice set their rate in their app. 1000 Hz is a common choice.
6
Plug in the laptop
Power-saving modes can reduce USB and Bluetooth responsiveness.

If only some apps lag, the cause may be the app's frame rate or your display's refresh rate rather than the mouse.
