Re: Is there a way to use the Dualshock 4 controller on Origins with my PC?

Dragon Age Inquisition only supports XInput controllers. You can try DS4 to XInput Wrapper to make Windows see the controller as an Xbox controller.

Note that this is no longer under development so I can't guarantee it will work.
