Yeah, I checked that out on the e-on set a few weeks ago when I first noticed it, very cool stuff to see Vue doing, I can't imagine what another software would try to do with so many polys. I tried opening up a 10m res dem file that was 25 megs in Autodesk Viz 2005 and it got about half way through before screeching to a halt and bombing out. So I cropped it down to a smaller area that was only 5 megs and even though it did actually import it, it was really sluggish to work with. By contrast Vue handles huge poly terrains via it's terrain editor extremely well, I think that's a lot of what makes it possible to do stuff like what the readers digest atlas showed.
