July 2025 - how to enable HDR in games ? (previous method no longer works?)

Issues & Assistance
1

Hi.

I played around with HDR months ago in Arch Linux and managed to get HDR in Jedi Fallen order (via steam) using something like

# gamescope -W 2560 -H 1440 --adaptive-sync --force-grab-cursor -f -- %command%

This doesn’t seem to work in cachyos ..

I have a HDR monitor, HDR enabled in Plasma/Wayland (and monitor) A 7800 xt and these packages

cachyos-znver4/lib32-vulkan-radeon 1:25.1.5-2 [installed]
cachyos-znver4/vulkan-radeon 1:25.1.5-2 [installed]
cachyos-extra-znver4/xf86-video-amdgpu 23.0.0-2.1 (xorg-drivers) [installed]
cachyos/linux-firmware-amdgpu 1:20250627-1 [installed]

What do I need to do to get HDR working now?

I was wondering the same, my games show hdr option greyed out despite enabling in the display settings.

I don’t see the Gamescope command --hdr-enabled in your command line. The better way to get HDR to work is to forget Gamescope and do this

PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 %command%

Nvidia users will need the vk-hdr-layer installed and add ENABLE_HDR_WSI=1 to the commands above.

thanks and that works for the Jedi game.

How about native Linux games? what options can I use ?

Thanks

You will need to have the game run in a Wayland session using SDL_VIDEODRIVER=wayland %command%. Again, Nvidia users will need to add ENABLE_HDR_WSI=1 to that.

I recently moved from Nobara to CachyOS, and now I can’t get HDR working no matter what I try. Everything that used to work on Nobara, I’ve tried here—but no luck. I also followed the suggestions from this thread, but still nothing.

Any advice on how to get Baldur’s Gate III running with HDR on CachyOS? I’d really appreciate the help.

EDIT:
So far this did actiavete hdr as it seems. Just would be great to do it withouth gamescope if possible??
gamescope -f -w 3840 -h 2160 -r 120 --hdr-enabled – %command%

Btw I’m on nvidia 4090 here

EDIT2:

found it in cae anyone else needs:
PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 ENABLE_HDR_WSI=1 %command%

this works for me oon baldur’s gate III
with cachyos proton

Hi all,
Total newcomer here. I come from Windows, and I recently got a HDR monitor. When I activate HDR according to this suggestion, I am able to chose HDR in Elden Ring. When I do so, the colors get super washed out. What am I doing wrong?

Back after a while to test again as everything that worked before just stopped working.. and it it is still not working. I tried every rick in the book, gamescope no gamescope.. it simply refuses to activate HDR…

whtas te state of HDR gaming on linux and with nvidia anyone got any game running with HDR at all??
