Proton 4.11-3

• Games will now attempt to access gamepads directly, instead of Proton emulating gamepads as if they were Xbox controllers. This means PlayStation 4 gamepads as well as fighting gamepads and other controllers will behave much more like they do on Windows. If you would like your gamepad to be emulated as if it were an Xbox controller, please use the Steam client controller mapping feature. If the controller cannot be accessed directly, due to a permissions issue, it will continue to be presented like an Xbox controller.
