No problems at all running Stadia through the chrome browser here, performance wise it's absolutely fine.
My only complaint, is the controller support in the browser itself before launching a game. I can toggle through games fine, even select one, but that last click that's required to sometimes load the game (when the big red play button comes up) wont activate without a mouse press.
Not sure if it's something my end that someone has a quick and easy "you're a pleb, this is what you do!", or if it's something known.
Hopefully a fix isn't far off!
@CookieMcCrumble : Same behavior for me too. I believe that that is just the way that it is implemented currently. Hopefully they'll get around to addressing it as a silent feature in due course.
@CookieMcCrumble It's definitely not just you. It happens to me every time whenever I start Destiny 2 while playing with controller. Make sure to submit feedback through the Stadia app. The more people sending feedback about the issue, the better chance it's getting fixed sooner.
