I am a newbie in DirectX and currently learning DirectX11. I have been assigned a task where I have to render our graphics in multiple windows (each window with it's own HWND), usually two(say Window1 and Window2).

What is the most efficient way to implement this ? We are using onboard Intel 4600 HD. It's not a fancy chip but gets the job done. Would appreciate some insights into this multiple window rendering.

The hardware we are using has two video outputs. We connect two physical displays (Display1 and Display2) to these outputs and each window is then rendered in it's physical display.

That is, Window1 will be rendered on Display1 and Window2 will be rendered on Display2.

    [This question](https://stackoverflow.com/questions/21292996/directx11-2-window-rendering) might be helpful. You could also render the scene to a larger texture (total size of your windows) and just present the correct piece of the textures to the right screen. That would avoid duplicating the draw calls for each screen. – Nico Schertler Oct 30 '18 at 09:51
