The killer feature here would be auto HDR for Linux. On windows apart from Win 11 autohdr, there is Special K and Reshade add ons that can do it for any game, so I can see them coming to Steamdeck very soon, but the dream is an official Valve implementation. I’d bet on it being on their roadmap.
I’ve been loving it. Played HL2 / Ep1 & 2 when I first got my deck, but original was unplayable. Now it all just works tho and I’m having so much fun. Movement speed is a tad fast!
