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’m still holding out on the next generation of steam controller for playing games ony deck while docked. Until then, my 8bitdo pro 1 has been wonderful.
