DXVK, the project that (since D9VK was merged) has turned into a massive translating unit of Direct 3D 9/10/11 to Vulkan has the first 2020 release available.
What is it again? Let's do a quick refresher! DXVK when fused together with Wine translates calls from D3D9/10/11 into Vulkan, usually giving you much better performance than standard Wine for playing Windows-only games on Linux.
Version 1.5.1 went up today and it includes a bunch of performance improvements for D3D9, an improved depth bias implementation in D3D9 fixing rendering issues (like missing shadows) in lots of titles, plus multiple other D3D9 bug fixes.
The number of threads used for pipeline compilation was tweaked this time too, hopefully reducing the performance impact on those with 6/8 core CPUs while also allowing CPUs with more than 12 cores to scale it up a bit. You can customize it with the dxvk.numCompilerThreads option.
This release should also make the gameplay experience smoother for GTA V, Halo CE, Need For Speed: Carbon, Risen 2, Sims 4, Trackmania Forever and Vampire The Masquerade: Bloodlines. Oh and the dxvk.hud option was restored since the accidental removal in a previous version.
