SteamOS supports HDR, VRR and Raytracing. Joshua Ashton (Valve Developer) gave a talk called "Rainbow Frogs: HDR + Color Management in Gamescope/SteamOS" at XDC this year where he explained how they improved colour management on Linux when other people have so far failed. https://www.youtube.com/live/Gg4eSAP1uc4?feature=shared&t=4011 https://www.youtube.com/live/Gg4eSAP1uc4?feature=shared&t=40... Melissa Wen (Igalia) talked more about how they're gonna try and upstream the work, but there are lots of moving upstream parts and they all move very slowly in "The rainbow treasure map: advanced color management on Linux with AMD/Steam Deck" https://www.youtube.com/watch?v=Gg4eSAP1uc4&t=4010s https://www.youtube.com/watch?v=Gg4eSAP1uc4&t=4010s There is also a talk by Friedrich Vock called "Improving the World's Slowest Raytracer" about how they're slowly making RT viable on Linux. https://www.youtube.com/watch?v=Gg4eSAP1uc4&t=27361s https://www.youtube.com/watch?v=Gg4eSAP1uc4&t=27361s Overall, a very interesting set of talks for anybody interested in Linux gaming.
