I'm not sure that's a fact, considering the DF video review says the opposite (they even say Tomb Raider is "night and day"). But he's definitely entitled to that opinion.
That they called night and day didn't impress me at all though. Yeah the image quality was cleaner with the supersampling, but I wouldn't call it night and day. And I really wouldn't call that a must have upgrade if all I had was a 1080p TV. Better framerates and actually more visual effects are more impressive, but few and far between as of now.
