Starting today, some lucky Xbox Game Pass Ultimate subscribers can stream games to their console instead of downloading them. This includes streaming Xbox Series X games to your old and crusty Xbox One. Of course, you can also stream games to your Xbox Series X or S, if you want to take them for a spin before downloading them, saving precious storage space.
Microsoft is slow-rolling this out to users globally with more folks getting access in the coming weeks. To help users differentiate, titles that can be streamed will have a “cloud” icon on the Xbox Store.
Of course, quality will vary depending on your internet connection. Also, if you have a data cap, you may want to be wary.
