I’m surprised I haven’t heard much about Collabora partnering with Valve before now. From reading their articles about it, it sounds like they’re largely responsible for the Deck’s update framework and for pressure-vessel which is designed to provide a standard linux container for games to run inside of (think of it like a flatpak but just for steam games).

Call me out if I’m wrong, but my Deck is noticeably snappier after this update. TF2 is also smoother, which is weird considering the game hasn’t changed visually at all. Not even an update notice of anything major.
