We are happy to announce the release of Wine Staging 1.9.6. This version adds support for Vulkan and fixes for various other bugs. This release adds a first version of a Vulkan wrapper to make the Vulkan API accessible to applications running in Wine. The work was started by Erich E. Hoover and later finished by other Wine Staging maintainers.
The code translates the Windows specific surface extensions to the corresponding X11 / XCB extensions and passes the remaining functions on the host Vulkan library. Although this seems to be an easy task on first sight, there are various pitfalls that make this wrapper more complicated than you might think. While the Vulkan API is almost binary compatible in 64 bit (except the differences in the calling convention), properly translating Vulkan calls on 32 bit turned out to be a bit difficult.
