Microsoft is giving an update on its support for Valve. Microsoft says that many of the titles from the Xbox Game Studios are not compatible with the Steam Deck. The titles don't work on the steam deck due to anti-cheat systems, and it's not clear if they'll ever be supported in the future.

The difference between the two can be small, like a warning appearing or having to invoke a virtual touchscreen. Some of them could progress to verified status soon.

You can install Windows on the Steam Deck to access games from the Xbox Game Pass. The option to switch over to Windows is open for Steam Deck owners. Last month, Valve's CEO said he was more than happy to work with Microsoft to get the Xbox Game Pass on Steam.

The full list of Xbox Game Studios titles can be found on the Steam Deck.
