I'd say just get a 360 controller and call it a day but if you must use a ps3 controller on pc, try ScpToolkit, its a bit cumbersome to get started but once you have it installed fully it should be able to handle a ps3 controller on any pc game
Issue with the PS4 controller is that the controller that I used up until now is starting to act up, so, I'm left with 1 controller again for god knows how many fighting games and playing certain games on PC would be better with a PS3 controller + I don't like Xbox controllers for fighting games. I'll try the toolkit, seems like the best option that I have in this case.
