Wait… There’s no HDR support? Is that true?

HDR is more important than high frame rates in many games, assuming you have a good monitor that supports it. Seriously, it’s amazing and extremely underrated.

The meme is kinda outdated. You can get HDR since KDE Plasma 6
Do game support it? Last I heard it didn’t work on any games
Valve did some work to support it in steam deck, it’s going to work its way upstream hopefully.
So it’s the answer “no”?
Probably depends on how much effort you want to put into it. Probably works in some distros with certain repos, but won’t work out of the box everywhere.
