The Xbox 360 and the Xbox One have long had PC support for their controllers, and is what a large majority of PC gamers use when needing to use a controller on PC.
However the same feature has not existed for the DualShock controller, which until now, has needed some “alternative” methods in order to get the controller working on PC. It is possible though, and I have done so myself to play games like Rocket League with great success.
Sony has hinted in the past that it was looking into PC support for PlayStation hardware, with Sony exec Masayasu Ito saying there was a possibility to Digital Foundry some time ago:
“The possibility exists since the PlayStation 4 shares many of its parts with the PC.
“At the moment, we’re concentrating on games so I have nothing to announce at this point, but we’re looking to expand in a variety of areas.”
With PS4’s around the world already packing the ability to stream the games to PC it seems the obvious choice for Sony to continue to add PC support, although it still has not said anything about cross-play with the Xbox One.
