I was looking for the most INefficient way to transmit bits from the CPU to the graphics card, to show that even doing things the more INefficient way should not saturate AGP-8x. If the inablility of Peter's AMD64 3200+ to display HDTV is not due to saturating the AGP-8x, it is probably due to running out of CPU. Is there another explaination? The AMD64 3200+ is almost the fastest CPU available. It should be loafing along with a large percent idle. Requiring a Cray supercomputer to watch television is not practical. And they probably don't have PCI-X slots. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
