Bug ID: 50136
           Summary: allow to disable wine's vulkan loader/driver
           Product: Wine
           Version: 5.21
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: winevulkan
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

I'm trying to run mesa's software vulkan renderer driver with wine.

This means I want to use vulkan's icd loader and mesa's renderer libs I built
(outside of wine):
libvulkan-1.dll
libvulkan_lvp.dll

Unfortunately, building wine with --disable-vulkan does not seem to disable its
loader, it only disables the driver:

$ VK_ICD_FILENAMES=lvp_icd.x86_64.json wine vkcubepp.exe
0064:err:vulkan:get_vulkan_driver Wine was built without Vulkan support.

Is there a way to disable the loader too ?

If you install the official Vulkan loader in Wine, it should be preferred over
Wine's loader. And as long as the loader doesn't try to load Wine's Vulkan
driver (which shouldn't happen when VK_ICD_FILENAMES is used), you shouldn't
get the "Wine was built without Vulkan support" message.

how does wine decide to "prefer" the external vulkan loader or its own ?
I mean I have the external loader dll libvulkan-1.dll in the WINEPATH, how is
it not taken into account ?

If you have a native 'vulkan-1.dll' in the DLL search path, that will be used
rather than Wine's builtin vulkan-1. You need to put your loader in the prefix
at c:\windows\system32\vulkan-1.dll (and syswow64\ for 32-bit).

If you're just trying to use the unmodified official loader, the LunarG runtime
installer is an easy way to install it:
