Can you try it with a DXVK master build? It might check the feature level on a D3D11 device and DXVK has returned something <12 until very recently.
Tried it with GE 35, which was re based from master 3 days ago, apologies if that's not the same thing.
Can we please have a proton log, hardware info, driver info, literally anything that would help us debug this?
Sure, here's the whole kit and caboodle.
https://gist.github.com/Bitwolfies/f12db2c5d7a7c5d0a304d51a08f6ea7d#file-gistfile1-txt-L47 looks questionable, seems like you're running on llvmpipe?
I tried it. It tries creating a device but it just exits right away.
With PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 VKD3D_CONFIG=dxr11 VKD3D_DEBUG=trace VKD3D_LOG_FILE=/tmp/lego.txt %command%
It creates a device, then a command queue and from there it just releases everything. Dunno really. I tried faking RENDER_PASS_TIER_2 support since it queries that struct, but doesn't change anything. I also tried VKD3D_CONFIG=dxr without 1.1, and no dice.
Today's Proton Experimental update has enabled ray tracing. I can now see the options, turn them on, see a visual difference, and see my frame rate tank. I was able to turn on all the different options, and everything seems to work correctly. The Proton changelog doesn't note anything relevant for this release.
Yes the experimental changelogs usually does not include all of the upstream changes and fixes.
Work has merged a couple of days ago so vkd3d-proton and dxvk together support D3D11On12 https://github.com/HansKristian-Work/vkd3d-proton/pull/1472
The only known problem right now afaik is that RT doesn't work on AMD RADV. But that is a driver issue.

When launching from Steam, you're given 3 options, Launch as normal, "compatibility mode" (appends -dx11 to launch) and "low spec mode" (uses a separate exe and appends -dx11) yet launching normally always places the game into DX11 mode, even when DXR 1 or 1.1 is enabled. My best guess is its unable to detect DX12 support, and thus forces compatibility mode.
I suspect a workaround like the one created for Control may be needed. https://github.com/HansKristian-Work/vkd3d-proton/pull/1190
Thank you!
