What the hell are you talking about? That is really not that "jaggerific." Really, it looks much better in the actual game. I wont lie, there are some jaggies every here and there, but when the cars are all in motion you will rarely see one unless youre really trying to look for them.
Polyphony doesnt spice up their screens like some companies *cough* microsoft *cough*. The replays always look better but rest assured that this game will have some pretty solid grafx locked firmly at 60fps.
Damn i sound like a salesman. uhg, well i just like the series a lot but im truely not biased by much. Meh, i dont need to convince anybody, i know im getting it.
If the deciding point for you is up to the grafics then i just suggest you dont get it.
