Issues with graphics plugins (Vulkan and DX11)

[Lord Puff]

After I read the September progress report, I think I understand why Vulkan does not work on my machine, but I'm still baffled by the D3D11 failure. I'd report it as a bug if I thought it was a bug, but I'm not sure. A quick google search seems to indicate I'm not the only one who has had the issue crop up, but no one ever posts how they fixed it or if it the problem went away on its own.
