A new Steam Deck Beta Client update was released with some new support and fixes. There is now support for the PDP Afterglow Wave Controller for the Switch and Turtle Beach controllers for the Switch 2. We also have a new 59.94 FPS framerate limit for Remote Play, the UI scale in Big Picture Mode should be fixed, and there was an occasional issue with the Steam Controller's B button that has been fixed.
You can download the updates yourself in the System Settings on the Steam Deck. Make sure your update channel is set to Beta or Preview for the beta update, while the stable update should just be available in any update channel.
