GT4s tracks are good looking, but I've seen better (in quite alot of games now). I think GT4p tracks are more aptmospheric then actually amazing looking. Most of them are bland race tracks anyway, where the only detail is the odd grandstand etc. The city tracks are ok, but certainly nothing new, nor amazing. The textures really need bumping up, and give it some bump mapping, and sort the pop up out. Meh, can't say it bothers me, but just making a point. The actual detail level is low.
(yes the car looks naff, but look at the scenery
see what I mean, this game is from like 4 years ago and on a dreamcast, yet the level of detail is still quite reasnable. OFC GT4 looks better, but the level of detail it self isn't really THAT much better on the city tracks.
Weird how this 4 year old game has a driver, skid marks, and reverse lights, yet gtp doesnt

That bugs me more then any scenery worrys!
