Just like it was done with the PlayStation 4 controller, would be awesome to see the same with the Stadia controller.
Currently, it “tries” to emulate an Xbox 360 controller, but doesn’t work pretty well. Works with a few games and others don’t.
If it’s possible, give the “native support” to this controller. Then, it will work properly with Stadia - in my case, Stadia works better within Shadow than my own connection - and less incompatibility like I’ve been seen right now.
