Make sure steam is not running, it will override RU. Also I usually have to make sure RU is not running any games before I plug the controller in or sometimes it will not work.
I'm sure you figure this out already, but you have to bind the keys to the controller button by pressing TAB and then input and setting the controls there
I use the same controller config as you, so I figured I ask. Computer detects ps3 controller as plug n play 360 controller now, so thankyou. Works for anything on pc, anything steam. Doesn't pick up on RU. Suggestions there? Thanks!
