    DelphiX Multiple Draw

    Thanks for the reply.[smile] Yes, the doWaitVBlank has been set to false, and the problem goes away. This was one of my tests. i should i mentioned it. [blush] So my understanding from that code is that each Draw box waits for the vblank to occur. thus the problem above. I will try to write a...
