I'm currently able to play BG3 in HDR (on Nvidia!) using gamescope. Once the Wayland stuff makes it to Bazzite, how would that change my Steam launch parameters? No more gamescope?

ENABLE_HDR_WSI=1 gamescope -f -w 3840 -h 2160 --hdr-enabled --hdr-debug-force-output --steam -- env ENABLE_GAMESCOPE_WSI=1 DXVK_HDR=1 DISABLE_HDR_WSI=1 %command% --skip-launcher

So the protocol is a blueprint of how to implement it. Kwin, Mutter and Gamescope are the ones implementing the code. Gamescope/Kwin already had HDR. What will probably happen now is slightly better accuracy and the removal of flags (your parameters) once they apply the new constraints.

Far out tyvm

I'm on AMD but I already play in HDR without gamescope with Proton-Tkg (Wine master).

For games I then only have to set DISPLAY= ENABLE_HDR_WSI=1 %command%.

The HDR layer is here: https://github.com/Zamundaaa/VK_hdr_layer

It should not be needed anymore pretty soon.

Could have been faster if you had helped them spec the color gamuts of the several different implementations, that's for sure.
