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

    Fixes Game Flicker:

    file: /etc/modprobe.d/nvidia.conf

    options nvidia NVreg_RegistryDwords="PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"

    General Wayland Fixes:

    These can also be set under modprobe, but I was troubleshooting a while back and it was easier to edit them this way before booting. So here’s my kernel parameters I have set:

    nvidia-drm.modeset=1 nvidia-modeset.hdmi_deepcolor=1 nvidia-drm.fbdev=1 nvidia.NVreg_TemporaryFilePath=/var/tmp

    ENV Variables

    LIBVA_DRIVER_NAME=nvidia
__GLX_VENDOR_LIBRARY_NAME=nvidia
__GL_GSYNC_ALLOWED=1
