Well that is the purpose of normal maps (in video games and cosoles), so you don't have to use a 200,000 poly object, you can get away with almost the same "look" with a 2,000 poly object. However the reason you may be seeing a bigger difference, is because maybe your object is too low poly. When they make a "low poly" version for games/cosoles/PC's that can handle thousands of polygons, they make an object that still looks smooth in silhoutte form, so it doesn't look low poly or have jagged edges. So low poly for a OpenGL or whatnot may be 2,000-10,000 poly's, while in away3d, 2,000 - 10,000 polys might just make Flash player choke. So unfortunately in Away3D you would need to cut that polygon count by ten maybe, 1,000 polys instead of 10,000. So it's much lower poly than you'd expect fromt the low poly in consoles and video games :/
