Recommended API and method

Fundamentally, sharing between processes is by way of DirectX 11 shared textures. OpenGL uses a driver interop to transfer from OpenGL. DirectX 12 uses D3D11on12 to transfer from D3D12. If you can use DirectX 11 directly, it is the most efficient way.

OpenGL uses an fbo blit to copy from the user texture to the interop linked, shared texture. There is negligible performance difference between send fbo or texture. SendBackbuffer gets the texture resource from the render target view. Again the time difference is negligible. The benefit is convenience if no texture resource is immediately available.
