As the title asks, how does one actually use HDR for games after upgrading to Plasma 6?
This was the feature I was most excited about, and I can hit the HDR button on my display configuration and it looks like the desktop is going into HDR mode, but so far I have had zero luck enabling the HDR feature in games. Every game I’ve tried had the HDR toggle disabled with no way to enable it.
I am running these games under Proton and I’ve tried both 8-GE and 9 Beta. Any tips?
Edit: probably important to note that I am using an AMD GPU under Wayland
I haven’t tested it myself, but you’ll need to install gamescope and the Vulkan HDR layer, then set the launch options to use it.
Of course, you’ll also need a monitor that supports it, and a cable that supports it as well (I recommend using a DisplayPort 1.4+ cable).
