DXVK

Provides a Vulkan-based implementation of DXGI and D3D11 in order to run 3D applications on Linux using Wine.

For the current status of the project, please refer to the project wiki.

Build instructions

Requirements:

• wine-staging for Vulkan support
• Meson build system
• MinGW64 compiler and headers
• SDL2 headers and DLL

Building DLLs

Inside the dxvk directory, run:

meson --cross-file build-win64.txt build.w64
cd build.w64
meson configure -Dprefix=/your/directory
ninja
ninja install

Both dxgi.dll and d3d11.dllas well as some demo executables will be located in /your/directory/bin. 32-bit builds are currently not supported.

How to use

In order to run executable.exe with DXVK,

• Copy dxgi.dll, d3d11.dll and SDL2.dll into the same directory as the executable
• Run WINEDLLOVERRIDES=d3d11,dxgi=n wine executable.exe

DXVK will create a file dxgi.log in the current working directory and may print out messages to stderr.

Environment variables

The behaviour of DXVK can be modified with environment variables.

• DXVK_SHADER_DUMP_PATH=directory Writes all DXBC and SPIR-V shaders to the given directory
• DXVK_SHADER_READS_PATH=directory Reads SPIR-V shaders from the given directory instead of compiling the DXBC shader.
• DXVK_DEBUG_LAYERS=1 Enables Vulkan debug layers. Highly recommended for troubleshooting and debugging purposes.
