Really? Is it a case like in FO:NV where they had to cut a bunch of stuff out so consoles could play the game smoothly?
Not sure, although it's possible, since originally the DC was intended as a Wii-U exclusive. There was a post by one of Mac port developers for DXHR (has since been removed from the Steam community page) that said the DC was actually based on an older build, which didn't have many of the later patches included in it.
