Valve has released the SteamOS 3.7.0 Preview, which introduces support for non-Steam Deck handhelds and improves various features like Bluetooth controllers and graphics performance. The update is still only available for the Steam Deck, but it brings several exciting changes.
The preview release requires users to set their Steam Deck’s update settings to “Preview” in order to access the new features. One notable feature is the ability of Bluetooth controllers to wake the LCD Steam Deck model. This update also includes improved support for certain displays and better performance when switching between desktop and game mode.
However, there are still some known issues, including compatibility problems with certain DNS servers and out-of-memory crash situations. Additionally, the developer notes that they are waiting to see if Steam and Proton will switch to Wayland in the future, which would improve accessibility for users.
Overall, this update is a step towards making the Steam Deck more versatile and user-friendly. As always, Valve encourages users to report any issues or suggestions they may have with the latest preview release.
