I have a PS4 controller set up with my Windows 10 computer. I have ds4 installed with the key map layout that I want to use for PSO BB but the game isn't recognizing any of the controller input. I know the controller is correctly set up with my computer because it recognizes input from the controller with other apps (e.g. I can type an "a" in a word document when I press left on the controller). Any idea why the game isn't recognizing the controller or how to fix it?
