The free and open source game manager Lutris had a small update focusing on having better Direct3D 12 support on Linux thanks to it now using VKD3D-Proton.
What is Lutris? An application you can use to manage Linux games across GOG, Steam and more along with support for scripts to manage Wine / Proton installs for Windows games and applications too. It's super useful.
It had quite a big update earlier this month so this recent update is on the smaller side, although still interesting. With Lutris 0.5.7.1, they now provide D3D12.DLL based on the VKD3D-Proton project as part of their provided DXVK runtime for Wine which they said will "help push updates faster and provide better compatibility for Direct3D 12 titles such as World of Warcraft".
VKD3D-Proton is the Valve-backed fork of the original VKD3D, which now serves as the official implement the full Direct3D 12 API on top of Vulkan for Proton.
