If you want to blit the whole desktop from one card to the other, you have to take into account that the b/w from the Radeon to main memory peaks at 132 MiB/s. IIRC that LCD you mention has a resolution of 1280*1024, which means you can transfer a maximum of 33 fps. And then you have to upload the data to the other card. Since it's an older one, chances are it's not going to be any better than 132 MiB/s (and realistically, it's going to be far from it). Assuming you manage to do this without hogging the CPU, you could have 33 fps with one frame latency. My experience with Radeons is that hoping for half the peak performance for reads is optimistic. -- Marcelo ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
