Microsoft says it worked closely with Valve to get the Xbox Cloud Gaming to work on the Steam Deck. It wasn't possible to use the handheld controls to play games on the Xbox service. The Microsoft Edge for the Steam Deck is now available in a trial version.
The community manager for Microsoft Edge says that they worked closely with Valve and the Xbox Cloud Gaming team to bring support for Xbox Cloud Gaming (Beta) with Xbox Game Pass Ultimate through Microsoft Edge.
Xbox Game Pass isn't available on Steam, so subscribers will have to stream titles from Microsoft's service instead.
The Linux version of Microsoft Edge now has support for the Steam Deck controls. Microsoft has instructions for creating a link to the cloud gaming service on the steam deck to make it easier to access in the future.
Just a few weeks ago, Microsoft detailed its Xbox Game Studios titles for the handheld. Another way to access Xbox Game Pass titles is via the Steam Deck, which is now able to run Windows. Microsoft's PC Game Pass is the only viable way to bring it to Steam at the moment, but Valve CEO Gabe Newell is more than happy about that.
