In steam some games ran really poorly and washed out because hdr wasn’t working. After some googling I found out that I’d probably have to run a gamescope command in the game’s launch options, and more googling and trial and error to get that working and hdr sorta dialed in. It’s good now, I get great performance and the hdr looks okay to my eyes, but it certainly didn’t go as smoothly as when I played the same games on my steamdeck and they “just worked”.
