HDR - NoobTaco/gnome-config GitHub Wiki
This is my documentation for getting HDR to work
Steam/Hero Proton
With Mangohud enabled - HDR
mangohud PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 %command%
Without Mangohud enabled - HDR
PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 %command%
NOTE: Be sure to run without HDR if first launch.
mangohud PROTON_ENABLE_WAYLAND=1 %command%
If that does not work (i.e. Battlenet launcher for first log in)
mangohud %command%

FSR4_UPGRADE=1
