Validation errors on Windows: index buffer creation flags

[GabrielMajeri]

I've run d3d11-triangles.exe on Windows 10 with the validation layers enabled.

Errors

Standard output is flooded with the following warning:

MEM(ERROR): object: 0x3 type: 10 location: 2985 msgCode: 400556898:
Invalid usage flag for Buffer 0x3 used by vkCmdBindIndexBuffer().
In this case, Buffer should have VK_BUFFER_USAGE_INDEX_BUFFER_BIT set during creation.
The spec valid usage text states 'buffer must have been created with the VK_BUFFER_USAGE_INDEX_BUFFER_BIT flag'
(https://www.khronos.org/registry/vulkan/specs/1.0/html/vkspec.html#VUID-vkCmdBindIndexBuffer-buffer-00433)

System information

• GPU: NVIDIA GTX 960
• DXVK version: latest master / 26ef59d

hope this helps in clearing all Nvidia issues..
right now crash is fixed a few days ago..
but for example ComputeMark renders black screen on all tests:
run on Windows putting dxgi.dll and d3d11.dll on program folder..
basically getting

Can't reproduce. Which version of the Vulkan SDK are you running?

The validation layers are independent of the GPU, driver, and platform used as long as the application runs the same code path, which DXVK mostly does, so this message is a bit werid.

Please try 0437e56, if that doesn't fix it, I have no idea what is going wrong. I double-checked the code, and anything that is used as an index bufffer in D3D11 is also created with the index buffer flag in Vulkan.

Can confirm the latest commit does fix the issue.
