malstraem / vulkan-interop-directx Goto Github PK

First of all, your project is a great demonstration of how to do interop between DirectX and Vulkan!

But I ran into an issue when running the WPF example on my laptop. My laptop has a dedicated Nvidia GPU and an integrated Intel GPU. When selecting the Nvidia GPU as the preferred card in the Nvidia Control Panel, it works fine. But when selecting the integrated GPU it crashes (device lost). I enabled the validation layer and found the problem that my integrated GPU does not support the D3D11TextureKmtBit as a ExternalMemoryHandleTypeFlag. It does support D3D11TextureBit though. But I can't just change the flag because then it also crahes (out of device memory, also with the Nvidia GPU).

Do you have any ideas about whether it can work with the D3D11TextureBit and if so, how to make it work?
