I have tried this on an Nvidia 1400 with 128mb and Nvidia 2500m with 512mb. The image remains the same. The only difference is that the 1400 has poor performance while the 2500m is able to manipulate the image. As a note, I ran it in vizard 2.5 and most of the image is there only the left and right most tiles are missing. Also note, I understand that in 2.5 only the tiles in the viewpoint are loaded. As I zoom out more tiles are loaded into memory. In 3.0 all of the tiles are loaded into memory prior to displaying the image. This was done to improve panning and zooming.
