Visual cues such as lighting have also been corrected in the final Prologue, and you'll no longer be blinded by reflected glare. The game looks much better for it too, with a more vivid and natural presence. The visual details here are nothing short of flawless. I looked, and looked, and looked...and couldn't tell the difference between the 350Z in the game, and the one in my garage - that goes double for the interior. They've even got the texture of the steeling wheel, and the windshield's sunlight repellent down. The car models are downright flawless - and the only thing to look forward to in the final Gran Turismo 5 is to have some of the some of the aliasing smoothed out. If you're wondering, yes, much of the screen tearing that plagued the game earlier on has been fixed too. I found that the game looks particularly fantastic on native 1080i and 1080p sets, plasma especially, as it minimizes whatever fragments of aliasing the game has (it isn't much)."
