If they make a windows app it will probably be like the one for YouTube music or messages app. They have the windows tile icon on there but when you open it, it's pretty much a chrome tab that doesn't let you do anything other than run the app. It will fill be cool to have one for windows.
@jerh4wk The Stadia experience is really built with Chrome in mind. I'm not sure that a standalone Windows app (which would probably just wind up being a wrapper for Chrome) would be a solution.
What issues are you having running Stadia in Chrome, and what troubleshooting steps have you taken? I don't have any trouble running it on my underpowered Chromebooks lol.
