It was pretty shit when I got my Steam controller. I won‘t sugar coat it. Inputs wouldn‘t even register for me when I tried to map it, there‘s no manual or support to help you with anything and the UI is damn confusing. Steam Imput being mandatory while not working properly meant I didn‘t really use the Steam controller for weeks. A recent update improved it a lot on my Linux machine, however and I can enjoy the controller now.

Still can‘t move actual gyro inputs into other software though. That still sucks. Hope they ditch Xinput soon or they make the drivers open source so someone else can build something better.

Steam input could be great. It‘s a great idea. It just isn‘t great right now.
