The game does not accept anything but DX12 now.
(I tried DXVK_FEATURE_LEVEL=11_1 because my GPU driver is not yet fully DX12 compliant.) I am welcomed by a fatal popup window. Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000010

I tried different proton versions. Game did not launch.
Proton 9.0-4 -- Game launches but freezes on black screen
Proton 8.0-5 and 7.0-6 -- Fatal error: [File:I:\AltWorkspace\Engine\Source\Runtime\D3D12RHI\Private\D3D12Adapter.cpp] [Line: 917] Missing full support for Direct3D 12. Please update to the latest drivers.
Proton 6.3-8 -- Runs with 15 fps for some minutes, then same error as with 8.0-5 and 7.0-6
Proton 5.13-6 and lower -- Missing Microsoft Visual C++ Runtime; Setup failing with Invalid ACL
Same issues with different proton-ge versions.
-dx12
Works out of the box
Install and play, no tinkering needed.

Weird behavior with the UE4 Installer, msvc140 was unable to be extracted. Works fine with GE, not with bare proton 8 / 7.
Does not work with DX12 (DX11 available in launch option)
Worked out of the box. No tinkering necessary

My hardware doesnt meet the minimum, but it runs alright.
Some issues with getting the game to render on my VR headset, but a restart fixed that.
