Gamepadla+ is a tool designed to help you measure the polling rate and synthetic latency of your gamepad. It provides accurate data on your controller’s performance, which can be valuable for gamers, developers, and anyone interested in input accuracy.
- Supports DInput and XInput protocols
- Available as both CLI and GUI for flexibility
- Offers detailed metrics, including polling rate and latency values
Gamepadla+ is a simple, versatile solution for testing and understanding gamepad response times.
uv tool install gamepadla-plus
pipx install gamepadla-plus
pip install gamepadla-plus
An installer and a portable release for Windows can be found on the Release Page.
- Execute the program
gamepadlawithout any arguments. - If you haven't connected any controller do it now and click
Refresh. - Click
Testand rotate the stick you chose slowly at the edge. - Optionally save the result to a JSON file or upload the result to <gamepadla.com>.

Gamepadla measures the delay between successive changes in the position of the analog stick on the gamepad, rather than the traditional input latency, which measures the time between pressing a button on the gamepad and a response in a program or game.
This method of measurement can be affected by various factors, including the quality of the gamepad, the speed of the computer's processor, the speed of event processing in the Pygame library, and so on.
Therefore, although Gamepadla can give a general idea of the "response" of a gamepad, it cannot accurately measure input latency in the traditional sense. The results obtained from Gamepadla should be used as a guide, not as an exact measurement of input latency.
Gamepadla+ or gamepadla-plus is a hard fork of Gamepadla.
The testing is based on the method of Christian P.: https://github.com/chrizonix/XInputTest.
