Symptoms

HDR (HDR10?) prevents Baldur's Gate 3 from rendering anything but a black screen. It seems as though DXVK_HDR=1 (set in my env variables) creates this issue. Removing it allows BG3 to render correctly, but without HDR at all.

Reproduction

The steam launch options I have for BG3 are: PROTON_LOG=1 steam-game-launch.sh %command%

The launcher renders. The game after it creates a black (gamescope) screen and the HDR10 errors in the log.

I believe a fix for this game may be disabling HDR10 if not HDR entirely. In my case I was trying to forcibly enable this with DXVK_HDR=1 and found this issue.

Note: I have a mixed-DPI setup. I run games in gamescope because Steam thinks my main 4k display is 2 x greater than the actual 3840x2160. My laptop display is scaled at 200% and creates this situation. I use the script below to correct this.

#!/bin/bash

# +40 FPS in PalWorld fix, seems like this forces the correct Nvidia libGL?
export VK_DRIVER_FILES="/usr/share/vulkan/icd.d/nvidia_icd.i686.json:/usr/share/vulkan/icd.d/

# HDR correctly detected in Horizon Forbidden West
# Broken for Baldur's Gate 3, possibly due to HDR10, not necessarily HDR being available
export DXVK_HDR=1

#exec mangohud "$@"
