Personally, I would really like to see Valve add a video capture feature. Like how on Xbox and PlayStation, you can press a button to record the last 30 seconds of gameplay. Something like this is almost impossible to do conviently on Steam Deck and just Linux systems in general. Valve adding it in natively to the Steam UI would be absolutely amazing.
Anyway, what features or improvements would you like to see on Steam Deck?
Today I learned that its pain to play together when your friend has the nreal glasses and you the Deck.
Why? You can only mirror your screen in Desktop Mode and not gaming mode. The desktop mode is hard to use when you don’t have an overlay, I think the asus rog would be easier to use without needing to close the game to navigate again. Big Picture in Desktop mode? Your game can be over it without having an overlay (played for the king).
I wish I also could easily duplicate the audio source with GUI instead of needing to google and use the terminal (but ateast its possible because no other platform can do this out of the box)
