I feel that isn't a fair comparison. The PS4 spec's were not even know at the time this demo was released, it was running on a high end PC. With the game 5 years in development it had to be ported to next gen after they were released, rather than being designed specifically for it. While I can't run the game on ultra on PC (because mine isn't powerful enough) I know it looks a lot better than PS4 from looking at comparable screenshots.
