We use the PAN ioctl to implement double-buffering for OSD0 graphic redraws on DM355, to good effect (after some hacking in the driver to get it to switch at the right vsync moment). We redraw a significant portion of our graphics every frame (PAL SD resolution). I don't know about 64xx but would guess it's similar. -- Jon Povey, Design Engineer [EMAIL PROTECTED] | +44(0)1280 825983 Racelogic is a limited company registered in England.
