NetDCU8 GDI slow screen update

    Hi everyone,


    I'm writing an application that creates a full screen window and then copies some bitmaps and draws a few lines to it. I'm currently using GDI functions to copy the bitmaps and draw the lines. I've made sure I only invalidate and redraw the regions that need updating to make things as fast as possible but the screen update rate is still very slow.


    I looked at using DirectDraw but this doesn't seem to be included with the NetDCU8 (at least the ddraw.lib file is missing from my SDK install).


    Can anyone suggest a faster method of drawing to the screen?


    Thanks
