The Wine project has announced the release of Wine 4.0, which brings with it official support for the Direct3D 12 and Vulkan application programming interfaces (APIs), even as Valve updates its forked Proton alternative to support non-Steam titles.Ī recursive acronym for ' Wine Is Not an Emulator', the Wine tool is designed to provide a compatibility layer allowing Windows-exclusive binaries to run on non-Windows operating systems including Linux, macOS, and Android.
