GE-Proton, the unofficial Proton variant by GloriousEggroll, has been released as a hotfix in version GE-Proton 11-9 - one day after GE-Proton 11-8.

Version 11-9 brings automatic HDR detection for DX11/DXVK and DX12/VKD3D-Proton under Wine-Wayland or Gamescope. The PROTON_ENABLE_HDR=1 and PROTON_USE_HDR=1 variables are no longer needed. It also fixes the menu video loop in Crimson Desert.

Version 11-8 includes updates to Wine, DXVK, VKD3D-Proton and other components, an automatic PlayStation-to-XInput fallback when Steam Input is disabled, Switch Pro controller support, AV1 decoding via dav1d, improvements for VRChat, Steam overlay fixes under Wine-Wayland, and opt-in Bluetooth LE support via PROTON_ENABLE_WINEBTH=1.
