Someone post some screenshots to compare please. I updated the game on my ipad 3 but i cant see ANY difference. With real racing 2, the difference is obvious.
It's not full retina, seems like a rushed resolution upscale. Apparently the next update will be a full retina update
Theres definately less jaggies due to 4x AA being used but apart from that I'm not seeing a huge difference. Maybe slightly cleaner looking but that could be down to the screen not the game.
Keep in mind, too, that Firemint added 4x anti-aliasing to Real Racing, which may be making the the change in quality more obvious.
