DX9'AdaterCount means monitor count.
DX11'AdapterCount meas video card count.
So I can.t get and use the second video card In DX9?
For example My laptop has intel/Nivida video cards.
I can't use nvida card audomatic only use code?
That means When I want use nivida cards with DX11 to render scene and share the backBuffer to DX9( in order to Interaction in WPF ) must update the DX11'Backbuffer with nivida'Device to CPU and new another Texture with intel'Device ,In the end share the Texture handle from DX11 to DX9 with the Same intel card.
