I’m on OpenSUSE with KDE Plasma and have HDR working with no problems in native application and Vulkan games, however when playing Windows games through Proton, the only way I can get it to work is through gamescope.
Launching gamescope for each game works but, from what I’m understanding, Steam expects an x11 window for the overlay to work, so it won’t open and this also breaks controller remapping through Steam input (which I often need).
My current solution is to open a new tty session and run Steam inside gamescope (which is similar to how it works on SteamOS) there. Is there a cleaner solution now, as what I’m doing now can a bit janky with some things?
Use Proton-GE! It has fixes to make the overlay work under Wayland.
I have been playing in HDR with a Steam Controller (which needs the overlay) for a while and it works perfectly.
HDR is great for TV/movies but kinda sucks for gaming anyway.
Most monitors are pretty shit at displaying HDR so it’s a common sentiment. The differences are massive (and hard to come back from) on an OLED.
I have a really nice OLED monitor. But most computers display things in a pretty simple colour pallet. HDR just makes everything look washed out.
If it looks washed out, it’s probably trying to display HDR without HDR being enabled properly. First of all, it requires Gamescope with the --hdr-enabled flag, plus it has to be enabled in the system and in the game, and it may also require some other environment variables.
It really needs to be simplified.
Steam Overlay works fine on Wayland if that’s your question
