I've been reading the news here latly and looking at the PS3 VS 360 junk but everyones choosing bad examples.
Some korean's have took the time to actually compare Ridge Racer 6 vs Ridge Racer 7. Both devoloped specifically for there systems. This will give turn comparision of quality of graphics.
All images are from gamebring news.
I'm not saying ps3 is weaker by any means but, it is very hard to program for. It might take devolopers over a year before they can reach 360 on texture quality. 360 is one of the easier systems to devolope for. I really think ps3 can handle more on screen but 360 does better lighting and textures.
Devolopers are defanitly having issues with getting textures and lighting effects correct on PS3 however most devolopers do admite they can normally get more on screen.
