I kinda do it, I use FWE and play with a gamepad. FWE adds extra stuff such as Sprinting and Bullet time, which require you to hot key these to a keyboard. So while playing I can walk around using my controller just fine, then hit the keyboard for all the extra stuff. The program I use it MotionJoy, Some people dont like it because it requires you to be online to use it, and sometimes when you install the driver it launchs your internet browser and puts up a asian website, so some people think its a virus. Ive been using it for 2 years and my computers been fine. Google it if your worried about it
