Game doesn't start

[Fox]

Hello there,

I'm having trouble starting the game.
Each time I tried to run I have an error message "DirectX 12 is not supported on your system. Try running without the -dx12 or -d3d12 Command line argument."
I tried many launch options, it doesn't work :/
Does someone have an idea of how I can fix this ? Please

My Spec:
Ubuntu 20.04
Proton version : Experimental; 8.0-3; 7.0-6 ; GE-Proton8-9 all of them give me this error
GC: Nvidia GeForce GTX 980
GC-Driver : 535.86.05
launch options that I tried:
-windowed
gamemoderun PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 %command%
gamescope -e -w 2560 -h 1440 --adaptive-sync --force-grab-cursor -f -- mangohud %command%
VKD3D_CONFIG=dxr11,dxr,force_static_cbv PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 VKD3D_FEATURE_LEVEL=12_2 %command%
None of those works...

When I try to launch with a -dx11 I have another error message "Unable to launch with RHI 'DirectX 11' since the project is not configured to support it" My guess is it means that Remnant 2 is straight up not compatible with -dx11 ..

Bump
Still waiting for some miracle :/

VKD3D_SHADER_MODEL=6_6 VKD3D_FEATURE_LEVEL=12_1 %command%

you need both of these in the launch option.
the game is not dx11. The game only is dx12

Hello Howbbp,
Thanks for your answer :)
Unfortunately since doesn't work... When I add thoses launch option I don't have the DirectX12 not supported error anymore, but the game doesn't load .. No window open up it just says "playing" on the big steam button
