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.
I just connect with Bluetooth like normal, and then in steam you can tell it to treat it like whatever type of controller layout you want: switch, xbox, playstation, etc.
That’s probably what they’re talking about. Instead of emulating another controller you have 1st party support.
