Grid:Autosport, pCARS, Forza Motorsport, Forza Horizon and Driveclub create it's atmosphere with the way the developers made the game as equally as possible. It may (arguably) never look as spectacular as a premium track and premium car on GT6 but you have to ask yourself...is it worth the collateral damage?
Just look at a game on the other end of the spectrum, Mario Kart 8, hailed by many critics as the 'best looking game' on next-gen consoles right now. Not because it's mind blowing, it lacks AA, but because the art style is pulled off within the confines of a 60FPS, 1080p environment and it just looks...engrossing.
PD seem to have their priorities totally mixed up. It just seems half-arsed.
