Forza 3... how can it have 1 million polygons per second

[NJ5]

edit - title fail, should say "polygons per car" of course.

Many people are talking about Forza 3 having 1 million polygons per car... is this really possible?

It's widely spread information that 360's GPU can do 500 million polygons per second (which is not gonna happen in practice since you need to use some of the shading units for pixels, they won't all be doing polygons).

At 60 frames per second, that's an absolute maximum of 8 million polygons per frame, which means the game would only be able to display 8 cars per frame, before accounting for environments or pixel shading.

My point? Stop hyping the game on the basis of performance numbers put out by developers, the game looks great no matter the amount of polygons. As for GT5 vs Forza 3 comparisons, wait for the games to come out because until then all we have are potentially manipulated screenshots and trailers.
