I just purchased vorpx, and I’m running into the same issues. The gamepad does not use the functions I’ve assigned to it, and it seems to use different configurations.
Sometimes triangle is “x/enter”, sometimes it opens my pip boy, sometimes it’s jump (new Vegas).
My controller was enabled in the games settings prior to installing vorpx. I don’t see the option in the settings anymore. I have settings for inputs via the steam gamepad configuration.
Also, if I disable head tracking, turning my head still moves the camera, but not the aim. Is that normal?
