Not going to name names, this isn't a vs thread.
I just played F4 less than a month ago at my buddies house and I have played it for several hours before. I mean it definitely looks better, there's just not a big jump in IQ IMO. Looks like Forza 4 in 1080p with slightly better IQ. As I said before, though, the car models look great.
Kinda the problem with a lot of next gen games though.
A lot of times you wonder if it's really that noticeable a jump from a ps360 game.
for example gta 5 vs watch dogs.
