I did a few tests today:

960x600,960x960: OK
1280x800,1280x800: jerky
1600x1200,1600x1200: jerky

As you say, it could be a hardware limitation. Perhaps it's hitting a maximum texture size limitation such as 2048x2048? It doesn't seem to be caused by number of pixels, because 1920x1200 on a single screen (2.3 megapixels) is smooth as butter, and 1280x800 on two screens (2.0 megapixels) is much jerkier...
