These controllers were all working on SteamOS before as far as I know, so I’m interested to see what this changes. My understanding is that previously their controllers just show up as generic xbox controllers, and now they will be properly recognized. We’ll see if this has any other benefits like custom bindings for back buttons and things like that.
Honestly I’d love to see more of this. Wheels and panels as well, not just gamepads. I’ve always wished for fully assignable controller support where the icon and HUDs etc change, ETS2 is looks so much better now that the icons don’t flicker twice per second because of my hodgepodge DS4Windows control scheme anymore. And with multi-button combinations and stuff making more things doable from the controller.
I do kind of wish Steam Input was a separate piece of software though, sort of like Xpadder back in the day. Some kind of open button-mapping standard with an API and everything.
