I suspect that one reason why Poser stuff uses such detailed meshes and textures is that it can get used for closeups. That figure is maybe closer to the (now free) Lo-res Vicky-1. In a game, moving, you wouldn't notice the lower quality. For another example, a cine film projected from 35mm has a huge image from a smaller effective frame than a 35mm still camera. Because it's a moving picture, we don't get a chance to see the film grain.
