Ello, I'm using my PC to Stream Steam to my Laptop in the living room. The Steam Controller works perfectly fine navigating Steams Big Picture mode on the Laptop and even launching games. When the game is loaded there is no input from the stream controller to control the game, I can However press the Centre button (with the steam logo) to bring up the steam overlay which is fully functional and also close the game. Upon the game loading there's a little steam notification in the bottom right stating that the steam controller is now controlling the game. Both PC and Laptop are using the latest versions of steam and are not using the Beta versions. Any Ideas? Cheers.
