There's no chance that new B-roll footage is direct feed gameplay. The difference in image quality is huge compared to any recent footage we've seen. It's even cleaner than Forza Horizon 2 which is 1080p with 4x MSAA.
Uh, DriveClub I.Q. have been better than FH2 for quite sometime, this shouldn't be a surprise. DC level of detail is simply on another level.
