Is wine-devel, currently on 5.16, already using Vulkan for DirectX 9/10/11 when the hardware is capable? Or it requires some adjusts? How can I verify if it is doing so?

I was using wine with DXVK untill a while ago, I noticed a considerable rise on performance, then I read that the wine's maintainers was going to provide Vulkan support for DX 9/10/11 on wine native code, and prior they provided only for DX12, but I see no difference in performance than before, I wonder if it requires a custom flag when compiling, or an environment variable exported when running?

I am currently on Ubuntu 20.04.1 and used this guide to install the latest wine-devel version. I have libvulkan installed, and a capable graphic card. Is there an easy way to verify if a running process is actually using Vulkan rather than OpenGL?

  • There are some clues of Vulkan in a dll called winex11, but none on the d3d9 neither d3d11... awkward... – Tiago Pimenta Aug 30 '20 at 13:57
