System Information

• GPU: Nvidia GTX 1080Ti

• Kernel version: 6.14.6
• Link to full system information report as Gist.
• Proton version: 9.0, hotfix, experimental..

I confirm:

• [X] that I haven't found an existing compatibility report for this game.
• [X] that I have checked whether there are updates for my system available.

Symptoms

The game "launches", but there's no window created nor any sound. The only option is to kill the process(es) using the Stop button. This seems a lot like #8682 though this game seems to use UE5.

Reproduction

With my configuration, the reproduction is just to install the game and try to start it.

Workaround

After trying all sorts of workarounds, including PROTON_DISABLE_NVAPI, PROTON_USE_WINED3D, WINE_DO_NOT_CREATE_DXGI_DEVICE_MANAGER -- without success -- I found a post by the developer from where I learned that you can use the options '-force -dx11' to force it from DX12 to DX11, and this worked.

Logs

In the default (non-working) case, the PROTON_LOG ends thus:
