That's really pretty.
Still, as with any racing game, the game-play is the most important thing. Driveclub and Project CARS both have everything to prove, regardless of beautiful screen shots.
As far as 30/60 fps, I don't care. I've had as much fun playing 30 fps games as I have 60 fps games. If the game is fun, that's all that I will care about. I've never once found myself thinking, "this would be so much better if it was 60 fps!"
