Do old areas of the world look better in the ToA graphics engine?
Yes, when you upgrade to Trials of Atlantis even the older regions of the world will look much better. Some of the more noticable effects seen in all regions will be fuller, more lush and life-like trees as well as an entirely new terrain texturing system that will make the ground look as detailed as the new trees. The new Atlantis zones will take advantage of the new underwater areas.
