Yep, its all about the textures. Because the maps are so big and detailed there is a lot of stuff that all needs to be stored in your memory for fast access. If its not all there as you move about the map it has to look on your hard drive for the info and as we all know hard drives are slow and that is why it lags.
Upgrading to 2gb made a HUGE difference to me. Before I got lag on medium settings now I can run with everything on high and not get any lag what so ever!
