Symptoms

I'm unable to use a Dualsense controller with Dark Souls: Remastered. These are my current controller settings:

The game behaves simply as if no controller is plugged in; no input from the controller affects the game at all, except for the touch pad, because that also controls the mouse. Portal 2 works flawlessly with the same settings (although it doesn't use Proton), so I'm certain the controller works. Enabling Steam Input in the properties tab does not fix the problem, nor does big picture mode. I haven't tested this with any other controllers because I don't have any.

Reproduction

As far as I know, just try to use a Dualsense controller with Dark Souls: Remastered.
