Lots of people noticed recently than a whole lot of working was going into the Gamescope project for HDR support, and now a Valve developer has teased trying it out. This has been a long time coming, with work needed to support it across multiple parts of the Linux stack but it's starting to get there now.
For those not aware, Gamescope is a micro-compositor that's used on the Steam Deck to display your games and it can also be used on desktop too. It gives you a whole lot of control over what games are doing, with lots of work from developer Joshua Ashton going in for HDR support.
Writing on Twitter, Valve developer Pierre-Loup Griffais mentioned:
New Linux gaming milestone: with the latest work from Josh Ashton, HDR can now be enabled for real games! Tested it tonight on my AMD desktop with Halo Infinite, Deep Rock Galactic, DEATH STRANDING DC. Very early and will still need some time to bake to be useful to most.
Griffais showed these shots:
An increasingly exciting time to be a Linux gaming fan and it looks like 2023 will be the year of HDR. As Griffais said though, there's a lot still to do and this is just the start of it actually working.
On their Fediverse account developer Joshua Ashton also showed off more of Death Stranding with a HDR Heatmap.
Not to praise on them too much, but Linus' quote on Valve saving desktop Linux seems to remain pretty on-point. I hope that he remains right on that (though I also hope his quote on Nvidia will no longer apply next year).
Quoting: basedThis is awesome, HDR looked great back in Windows, hope we get it going on Nvidia as well :)
According to discord, the HDR implementation is on Gamescope, so we might need Nvidia proper support for it first.
