It looks good. Car models and lighting are fantastic. But the environments, well they definitely need some touch-up but I'm sure they'll do that in the final touches.
I heard someone comment that it was photorealistic. I say to that person, they need to go outside more haha.
Can you compare that to other games? Well sure you can. Certain genres shouldn't be excluded just because of certain technicalities. But on a technical level, I think what has been done in God of War 3 and Alan Wake and Uncharted 2 are a little more impressive than what is being done in GT5 just for the sake of what they have created rather than replicated.
But a lot of people are excited for this as they love their simulation racers. Me? Well I just don't like simulation racers at all but that's why they have so many different genres. Different strokes for different folks.
