I honestly think it can since Watch Dogs is a cross generation game and the graphics aren't that great compared to other games like Infamous Second Son and Killzone. Those run at 1080p at 60fps with the exception of Killzone's MP running at a lower resolution than 1080p and SP which runs at 30fps. How does a Radeon 7850 perform in Watch Dogs? If it can run it at 1080p at 60fps then PS4 can run it at 1080p at 60fps, too.
