VK_ERROR_INCOMPATIBLE_DRIVER when running vulkaninfo.exe on AMD R9 280

Vulkan
1

I’m on Windows 10 x64, my graphics card is a AMD R9 280. I have the latest AMD Vulkan beta drivers, as well as the Vulkan SDK and I have restarted my system several times.
When running the “vulkaninfo.exe” from the SDK, I’m getting a VK_ERROR_INCOMPATIBLE_DRIVER:
[ATTACH]92[/ATTACH]

Trying to run any of the demos will result in a similar error:
[ATTACH]93[/ATTACH]

Am I missing something else?

Somehow AMD does not support Vulkan 1.0.3.1, whatever the difference is. And SDK for 1.0.2 is unavailable on LunarG. Run vulkaninfo from C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Vulkan 1.0.2.0\Demos
To compile samples, find

    const VkApplicationInfo app_info = {
        .sType = VK_STRUCTURE_TYPE_APPLICATION_INFO,
        .pNext = NULL,
        .pApplicationName = APP_SHORT_NAME,
        .applicationVersion = 1,
        .pEngineName = APP_SHORT_NAME,
        .engineVersion = 1,
        .apiVersion = VK_API_VERSION,
    };

And replace VK_API_VERSION with VK_MAKE_VERSION(1, 0, 2)
This is ridiculous if you ask me, but will do fine as a workaround.

Thanks, that did the trick. Guess that’ll have to do for now.

Yeah, there was a late bump to the API version used by the SDK that landed after we’d baked our released package. We’ve updated the web driver at http://support.amd.com/en-us/kb-articles/Pages/Radeon-Vulkan-Beta.aspx and this version should now work. Let us know if you’re still having compatibility issues.

Cheers,
