Hay Daddy, Still no joy getting it working. [blush]

I dont know where to start.[blush] any pointers pls?

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...

Hello, Im creating a GUI with DelphiX. im using this to make it look good, when the images move quickly. Which works fine, i get 60FPS, about the fastest possible frame rate. But....(you know theres a but) when i add another draw box and draw on that the fps reduces to 30fps. and if i add...

Thanks jb, I have now solved this problem. using directX. This ensures that tearing does not occur. woo hoo. and all the timing is hunky dorrey! thanks again Jim

Thanks Erm dont seem to be able to get this to work. Possible to email the project? or msn? jimyhunt {at} hotmail [dot] com

Thanks for the reply. Ive now tried the option to hide the buff image outside the screen, but nothing is drawn. :( Heres my code: Buff.Repaint; //Draw Stuff onto Buffer Paintbox Buff.Canvas.Polygon(NeedleCoord_Left); //Copy Buff Paintbox to Image...
