Everyone has their own opinion and issues about games. I take them as a grain of salt, like the dude trying to compare DC to 3 year old Dirt 3 which that comparison is simply off the wall baffling because of the sheer amount of graphic effects DC is doing along with the extreme track-side details. The AA seems perfectly fine from what I've seen, is it high end PC quality AA? Well of course not, this is a console game but for a first year PS4 title and yet still is able to be the best looking racing game to date including anything on PC....i think DC has truly raised the bar for racing game visuals and this is simply coming from a unbiased PC gamer that i am.
Take the blatant negative comments in here as a grain of salt and judge the game with your own tastes,etc...we all of our opinions and tastes or things that bug us about games but it don't mean its true to the next person.
There is one thing for sure, this game is solid and from the feedback i have read and heard from those that have have the game now...its been nothing but 98% positive, mostly saying the gameplay is really fun and exciting and visuals are bar none set above anything else. And to think this is a frist year PS4 title that will be supported for months to come with new tracks, cars, weather addon pack,etc for free, mind you!
