There's so many incredible things going on around Wine right now it's hard to keep track. DXVK is now expanding to support Direct3D 10 over Vulkan in Wine.
Talking about it on the official GitHub account in this issue, the main developer of DXVK said it works in a similar way to DXUP with it being a "very thin wrapper around the existing D3D11 interfaces, while allowing for better interoperability between the two APIs.".
As for how much it actually supports, well, quite a lot. It implements "most" of the Direct3D 10.1 core API and the shader reflection API. However, the Effects API is not currently supported. To use it, you will need the d3dcompiler_43.dll, which can be grabbed by using winetricks.
More information on it here.
Additionally, there's also another new project named Direct3D 9-to-11 which aims to convert Direct3D 9 programs to Direct3D 11. It's supposed to be used with DXVK and it's currently under "heavy development". It will be interesting to see how this project shapes up, although there is already the VK9 project to keep an eye on.
So much Wine, so little time.
