| Env var | Explanation |
|---|---|
MACH_DEBUG_AUDIO=true | enable verbose audio debug logging |
Linux
On Linux, Mach binaries have both Wayland/X11, and Vulkan/OpenGL/GLES support built-in (loaded dynamically via dlopen.)
Mach will try to use Wayland and Vulkan first. If Wayland is unavailable, it falls back to X11 automatically. If Vulkan is unavailable, it falls back to OpenGL.
| Env var | Explanation |
|---|---|
MACH_FORCE_BACKEND=x11 | force the use of X11 backend only |
MACH_FORCE_BACKEND=wayland | force the use of Wayland backend only |
MACH_FORCE_GPU_BACKEND=opengl | force the use of OpenGL backend only |
MACH_FORCE_GPU_BACKEND=vulkan. | force the use of Vulkan backend only |
MACH_FORCE_GPU_BACKEND=opengles | force the use of OpenGLES backend only |
Windows
On Windows, Mach only officially supports shipping applications with Direct3D.
Sometimes it’s helpful for developers on Windows to test the OpenGL, Vulkan, or OpenGL ES backends on a Windows host. We don’t support shipping games in this configuration, but they can be enabled via build.zig (OpenGL ES support varies across drivers, Vulkan depends on the heavyweight LunarG Vulkan SDK. OpenGL is generally always available.)
macOS
On macOS, Mach only supports Metal.
