YouTube user RajmanGamingHD has uploaded a couple of videos comparing the PS3 and PS4versions of the upcoming Assassin’s Creed IV: Black Flag.
Here’s a full screen graphics comparison for Assassin’s Creed IV Black Flag between the PS3 and PS4 versions.
Both footage is an in-game cutscene from the start of Sequence 3, and both have been captured @ 1080p via HDMI using the Elgato Game Capture HD.
Remember to select 720p or 1080p HD when watching them!
