A new update for the Steam Deck has made its remote play together option “completely functional”.
This will cover those hosting and those joining a game session. To try it out for yourself, all you need to do is select a game that supports the feature, then head over the Quick Access Menu and you should be ready to roll.
As well as updating this feature, users will now also get a message letting them know when their Deck is running out of space. A notification will pop up when there is less than 2GB of space remaining.
