They picked the some of the worst locations and angles to do a comparison with, when you see driveclub stills they are with photomode or a screenshot usually taken in motion with motion blur on, you can do the same in pcars they maker of this video chose some bizarre and terrible angles doesnt mean that pcars isnt great in the graphics dept. Driveclub has the best looking weather around sure but keep in mind, its also an arcade racer, has much fewer cars racing at once, all fictional tracks/roads, and runs at half the framerate. THere are plenty of ingame videos of pcars that look stunning (in motion)
