PC drivers for the Xbox One controller are available now for eager gamers, thanks to Major Nelson.
According to Hyrb, the drivers will be bundled in a future Windows update, but for those who can’t wait, you can download the drivers in 32-bit and 64-bit flavors from his blog. Any PC title that had compatibility with the Xbox 360 controller will automatically work with the Xbox One controller once the drivers are installed.
