the new graphics will have the same size/resolution as the old graphics, they will just look better.   Also thers rarely any flyunder pic to find on the map, all used lvz graphics are afterbackground images that are sticky. Plus thers no animation (the motion of the cp's is mainly controlled by the bots turning on/off pictures. What takes fps is big animation files that need to be run. So even though the zone will look flashy, i think its not gonna be 2 performance hungry.
