            Bug ID: 46198
           Summary: Xenia fails to find Directx 12 graphics adapter
                    [vkd3d]
           Product: Wine
           Version: 3.21
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: chridye at gmail.com
      Distribution: ---

Xenia seems to startup just fine but when it gets around to setting up the
directx 12 subsystem, it fails to find a suitable adapter. Xenia goes about
finding a suitable adapter via IDXGIFactory2::EnumAdapters1. It only requires
feature level 11_0. 

the important bits: 

I built wine from source on ubuntu 18.10 with support for vkd3d (or at least,
the build system said there was). I have nvidia 410 drivers installed.
gears-vkd3d ran. 

vulkan doesn't crash at startup (wine64 xenia.exe --gpu=vulkan)

Directx 12 is used by default so just simply using wine64 xenia.exe is enough
to cause the problem. 

This works consistently on Windows but is non-operational on Linux under wine.

The latest Xenia build can be found at 
https://ci.appveyor.com/api/projects/benvanik/xenia/artifacts/xenia-d3d12.zip?branch=d3d12&job=Configuration%3A%20Release

To summarize:
Xenia fails to find a graphics device with a suitable feature level under wine
when one should exist.
