I know my DS4 works with my PC because I've at least tested it with one other game, which is Street Fighter x Tekken. I use Input Mapper to make my DS4 work.
But now when I try to play ACR, the option to use a gamepad doesn't even appear when I go to the options menu, all the options are just for different keyboard settings. And I don't know if this helps but my DS4 is emulating a 360 controller in Input Mapper.
Also I'm not sure if I should post this here or in peripherals...
never mind I "fixed" it myself, just used DS4Windows and it worked, guess it's the superior program
