We have just shipped an updated Steam Deck Client to the Stable (default) channel. General Improved library performance for users with large numbers of collections.

Fixed notifications for achievements not firing when offline. Fixed a case where the wrong FPS limit could be applied on startup.
been wondering the same thing myself. there was a lot of news about it a couple of months ago but not so much anymore, i think
