I am making an app that scrolls information on the desktop. The window is transparent. I am starting out simple, trying to find the lowest CPU use for animating things and
Ok, I just solved the problem after posting my previous statements. It turns out I hadnt installed my graphic drivers on this computer yet, and after I did it started working very smoothly. Perhaps it was using some software graphics rendering previously or something. So I recommend you update your graphics drivers to the most recent available to see if this helps the problem. The original poster seems to be having a different issue however, since it seems he has his fx drivers properly installed. I am not sure if there are any problems with nvidia 8800 cards with directx though.
