His plane has possibly more manipulators than the MU-2. Though I don't know exact figures on both, there must be in the ball park of 150 manipulators in the ERJ. That's quite a lot and every ATTR command slows down sim (Manipulators are ATTR commands), then you have 6 2048 by 2048 maps, each with a normal map, then somewhere with 300,000 polygons, + or - 50,000. When you look at it that way with all the manipulator code, polygons etc, the performance hit isn't as terrible as some of the people on the .org are making it out to be. -TheoGregory
