If nothing works download DS4Windows, it allows you to map a PS4 Controller to any button on your keyboard, also allows windows to detect a PS4 controller as an Xbox360 one.
Viewing post in (SOLVED: GAMEPAD FIX + REMAP) no PS4 controller support?
@wheelchairgam3r yes it does! just tried. after you start the game in Big Picture mode, press Shift and Tab, then click Controller Configuration, then set to how you want. i duped L2 and R2 to my Right Analog stick Left and Right movement.
