Gets a touch anorak-Y (surprise) but on the whole, they're impressed. The bit about the possibility of MS doing a cheap Switch-style device with this pre-installed is intriguing, but also is it being on Switch itself.
I've got a free Stadia pass going. You get Stadia Pro for 3 months. Currently that'll give you Destiny: The Collection, Samurai Showdown, Farming Simulator, and Tomb Raider Definitive.
You'll not be able to play this on your tv yet as they've not updated the existing Chromecasts in the wild yet. No idea when the plan to do this is.
It'll work in any Chrome browser with most controllers.
I also tried this since it had the free 2 month Pro thing.
I've got a BT fibre internet pipe to the house at ~70meg maybe and running it onto a browser window on a 1440p monitor.
Downloaded the Stadia.. bit weird as I seemed to have to do it from your phone to get it all fired up? Got over that and then tried the driving game? Sprint? Sploot? Zoom? Can't remember off the top of my head but it's the newish Codemasters remake thingy I think?
Now with the caveat that maybe 4 other people in the house were trying to play Fortnite, Apex or Rainbow 6 at the same time... I can confirm that it's a janky mess that fairly stuttery and broken. At a guess I'd suggest that it would probably work fine if I had more bandwidth to get to it but it highlights a significant problem as far as I'm concerned.
The tech will likely work well enough if you can make sure that it gets a large amount of a currently ok UK internet pipe. If you're in a property that has competition for the pipe then it doesn't work for a driving game that I'd want 60fps and 1080 minimum on a PC.
Maybe the demands if you're using a mobile version is less?
tl;dr I tried it.. I didn't like it. I'll not keep the Pro version going after the free window that's for sure.
