Developer Philip Rebohle has pushed out another major release of DXVK, the Vulkan to D3D layer used together in Wine and Steam Play.
Boasting a new feature set that pumps up the available Direct3D support to 11.4. However, certain optional features are not currently supported like Tiled Resources, Conservative Rasterization and Rasterizer Ordered Views but they may be added if ever needed. This should fix a crashing issue with Plants vs Zombies - Battle for Neighborville, which requires at least D3D 11.3.
Additionally, support for DXGI (Microsoft DirectX Graphics Infrastructure) was boosted up to version 1.5 which allows applications/games to check for HDR support but DXVK itself does not currently support HDR. Some games seem to need the interface for HDR to be there even if not used. You should also find the Rockstar Game Launcher working better with this update to DXVK, with new support for GDI interop with DXGI surfaces. Although the launcher does need some other Wine fixes due to a bug in Wine's Direct2D support.
Some resource mapping improvements were also made with the "d3d11.allowMapFlagNoWait" option enabled by default, possibly resulting in some games performing better. Developer Rebohle asked if you see regressions, to try if setting "d3d11.allowMapFlagNoWait = False" in the DXVK config fixes it when reporting a bug.
There should also be some possible performance improvements. One such change is games that make heavy use of Deferred Contexts with both Dark Souls III and Sekiro: Shadows Die Twice being mentioned as hopefully improved. There's also a possible CPU overhead improvement with more accurate resource tracking.
