Microsoft is moving into the next phase of its plan to bring Xbox Cloud Gaming to as many devices as possible, and it’s one of the most important steps yet. Starting this holiday season, Xbox Game Pass Ultimate subscribers will have access to cloud gaming on Xbox Series X/S and Xbox One consoles.

The company, which made the announcement during its Gamescom showcase, said you’ll be able to fire up more than 100 games without having to download them first. At some point in the future, Xbox One owners can play some Series X/S games through the cloud, such as Microsoft Flight Simulator. You’ll know a title is cloud gaming-compatible if you see a cloud icon next to it in the Game Pass library. Microsoft is targeting 1080p gameplay at 60 frames per second.

Xbox Cloud Gaming is already available on phones, tablets and PC. Microsoft is also working on Xbox game streaming sticks as well as a smart TV cloud gaming app. This summer, the company started transitioning cloud gaming onto beefier Xbox Series X hardware after launching the service on Xbox One S-based blade servers.
