Anyone have an idea on how to implement DX11's draw auto in DX12? I need to bind a Stream-out from a Geometry shader as a Vertex Buffer, but not sure whats the best way to to fill in the arguements for the ExecuteIndirect. I'm guessing I'll have to use a Compute shader to generate that, but I'd like to avoid that if possible.

ResolveQueryData worked out in the end, making sure everything is barriered properly was the most difficult part.
