The game has been optimised for m&k on pc. I jammed with a controller for a bit initially but swiftly moved over once I got to the pvp side of things....
LOL you can use a Controller Xbox One / PS4 controller on PC if you use Xbox One Controller will have an Xbox One icons if you use PS4 controller it will have a PS4 icons. you will see a big difference from 60fps to 30fps. I play on PC more than my PS4. I use controller all the way.
No don't as many I made the move to pc used pad for a little but I was getting outplayed so just started practicing on k&b I'm doing a lot better after a few weeks practice
