Symptoms

After initiating EAC, the game opens up with a white screen and closes abruptly. Same thing happens in Windows, but in my specific case is fixable by using modded dx12 dll's from this github (my gpu does not support the level 12_0 required by the game, but this can be fixed with this patch). Was thinking that when using proton this issue would not happen, since my gpu works with Vulkan just fine, but I guess the issue lies somewhere else.

Things I've tried, and some of my findings:

• I've noticed, by watching nvidia smi while the game boots, that the gpu is not initialised by the time the game crashes
• Tried steam native, and steam flatpak
• Tried using both X11 and Wayland
• Tried using a bunch of enviroment variables, none worked.

Reproduction

Simply launching the game
