Recently I bought a wireless third party controller for gaming on PC "Spartan Gear - Ksifos Wireless controller for PC-PS3". Now my problem is that Windows detects the controller as an Xbox360 controller when the controller itself looks more like a ps3 controller and it has ps3 buttons. Which is extremely confusing since the game I want to play (Batman Arkham Knight) with a controller, displays buttons as xbox buttons (Y,B...) when on my controller the buttons are PS(X,square,circle...). What could I do to make windows recognize the controller as a PS one...Or just for the game to recognize that my buttons are for PS3 not xbox. Here's a link to my controller: http://spartangear.eu/product/ksifos-wireless-controller-for-pc-ps3/
P.S. : Im not really sure if this is the right place to post it, but Im pretty desperate at this point...
Thanks in advance!
