Hello @TheM1Stery, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/8626#issuecomment-2845812523.
proton 9.0-4x1 2025-05proton experimentalx1 2025-05
Compatibility Report
System Information
I confirm:
Symptoms
Dualsense stops working after you turn off the mouse or the keyboard. You need to restart the game for the controller to work again.
Reproduction
Don't use Steam Input (the game natively supports Dualsense). Start the game and connect your controller to the game. After just turn off your mouse or keyboard. Also connecting a keyboard or a mouse reproduces this bug.
This did not happen on previous version of Proton Experimental. I also checked Proton 9.0-4 and that bug doesn't occur there
