Unofficial XONE controller drivers below.
NOTE: This is provided as-is. Please see the videos on how to install this in either Windows 7 or Windows 8. If you wish to wait for official support from Microsoft, PC compatible drivers are supposedly being worked on by Microsoft. (Then again, they may not be working on it as well.)
If you have issues with the Xbox 360 controller (i.e.- Triggers not working or driver issues especially with the
unofficial drivers) or do not want to go to the trouble of attempting to get the PS3 or
PS4 DualShock controller working in Windows for FFXI or FFXIV, you can give the XONE Gamepad a try. If going by the ArsTechnica article, you may need the non-free XPadder application for the XONE Gamepad to work in certain games.

Quote:
Thankfully, another hacker made his own attempt this month before conferring with Microsoft, meaning that Windows users can finally add next-gen pads to their PC arsenal. At this time, hacker Lucas Assis' patch is quite inelegant, even though it received an update last week that fixed issues with the controller's triggers. You'll need to install an unofficial driver and two applications (linked in the video tutorial above) before the controller will even work, and you'll probably want to install the paid XPadder app afterward to enjoy full support for your Steam library. Many games we tested didn't work without that latter addition tossed on top.
