At its most simple, the Xbox Cloud Gaming service arriving on Xbox One and Xbox Series X/S will allow you to stream games and try them out before you commit to saving them to your console.
Microsoft has finally started to roll out Xbox Cloud Gaming – the feature formally known as xCloud – to Xbox consoles.
But there’s another, more important application of the service on console: the service will also eventually allow you to play Xbox Series X/S exclusive games – like Microsoft Flight Simulator – on Xbox One, though that won’t be viable at launch.
Microsoft previously said the public can expect access to this feature by holiday 2021.
