Diference between Clipping rect and invalid rect RRS feed

  • Question

  • Hi,

    I am not sure about the difference between clipping and invalid rects and how to decide which one to use.

    Clipping rects are specified in between BeginDraw and EndDraw but invalid rects are specified when calling Present. But, both restrict the back buffer copy area.

    Could someone please explain the kind of improvements by clipping and invalid rects? And how to decide which one should be used?
