Since we have nothing else on PS4 to compare it to yet, I'd say that Driveclub's 1080p, 30 frame-per-second graphics are roughly on par with Forza Motorsport 5's 1080p/60fps looks. I'd give the slight .edge to Forza when making a mental comparison, but I'd have to put them side-by-side in order to really make a call. But this isn't a console face-off; PS4 .players are certainly not going to be disappointed by Driveclub's looks.
Strange b/c you certainly acted like it was. Placing your console of choice in the winners circle. I am very curious to know what gave fora 5 the edge in the looks department? If I had to guess I'd go with the crowds and lighting but that's without putting them side to side.
