I think its LOL worthy how some users complain that this game is a step down from Uncharted 2. Uncharted 3 is a graphical beast. That same design philosophy of absolutely amazing textures, beautiful lighting, and pathos beyond comprehension is still there.
....but it isn't without its sacrifices.
Motion blur is gone? Yes.
Aliasing is more obvious? Yes.
However, what you get with the trade off is a FAR more detailed experience. Uncharted 2 was a boxed game with most levels being small, closed, confined areas, however, Uncharted 3 approaches a more open world game design approach where you'll see some HUGE levels with massive undertakings.
It is without a doubt a techincal sight to behold, however, there will be sacrifices.
