I’ve been using scope buddy to manage my gamescope config, has auto resolution/hdr detection and you can set global defaults. you still have to pass scb -- %command% but it seems easier to manage. with proton 10 i set it to actually disable gamescope and use it to set the proton Wayland+hdr env variables and haven’t had any issues so far.

my recommendation if you do is to look at refresh rate, going 120hz to 240hz felt like a much bigger upgrade to me than sdr to hdr. especially if you’re playing games that depend on response times, it just feels smoother. hdr in Linux is decently there on kde but there’s still issues getting it to work everywhere like Firefox, though they still look nicer than regular sdr imo. also avoid hdmi, especially if using amd!

this would make an interesting sequel. I Have No Eyes and I must scream
