I assume it works by re-rendering the scene, smoothing any edges and adding some more reflection details. I think it's pretty impressive it can do that in such a short time. Obviously the actual gameplay can't look like that, but it should be pretty sweet nonetheless.
Car porn is awesome. I still want the full list of cars though.
My point was that its not a computer render image. Its a shot from inside the game. When you go into photomode in forza 2, it adds more AA to what the game is already running to improve the quality for close-up shots. Forza 2 already looks fantastic in-game, and that was using technology from 2006/2007 so i can only imagine forza 3 being better. Have you not seen HD gameplay videos of forza 3? It looks amazing, and there is no doubting the fact that the graphics are going to be better than its Predecessor.
EDIT: Just to point out. Compare the shots to forza 2 ones. Much better. The textures and reflections never got changed when entering photomode, so we atleast know the game is going to be close looking to them shots, even when racing.
No, your just blind. Look at the small blue car coming round the corner with the white spotlight covers. Quite obviously an RS200.
That or evolution has failed to give you the same eyesight as the rest of our species. I actually think there are plenty of experts on this forum, I am willing to bet they could also identify the other blue car and the yellow car from that picture.
