It's not so much the amount, but how much of it a game like GT5 can be
done in the studios not at runtime. GTA has to dynamically light every
surface at runtime because sometimes it's night, sometimes it's day,
sometimes it's raining etc.. The color, shading, reflection and
lighting of the scenery in GT5 is always the same and therefore is
simply pre-drawn artwork. That's why they always shy away from car
damage, since it has to be done at runtime, not months before at the
developer studios. Car damage will hit their frame rates massively and
they'll have to make cuts elsewhere. The tracks scenery is always
drawn to be seen from a certain angle too. This helps them to 'fake'
shadows and reflections by literally drawing them onto the images. In
GTA you cannot rely on the viewing angle of the player since they have
*so* much more freedom. The shadow and reflection effects have to be
done in real time. The same goes for Burnout Paradise, which looks
superb, but everything plays at the same time of day and with the same
conditions (though of course it has car damage). GTA actually has the
better and more accomplished graphics engine of them all, but the
nature of it means that it can look poorer in a simple side-by-side
screenshot, but when you see it going, it looks *far* more realistic
and far far better.
