I've personally had more issues with this game than with AC Unity. More issues with random stuttering, crashes, etc. Seems to be more demanding on the CPU side too. The overall performance isn't much different than AC Unity, but frankly it doesn't look as good. It's a cross gen title and it's very demanding. Hell, most games lately have been in this same ballpark as far as how demanding they are. So why does Unity get all the hate for supposedly being "horribly optimized"? For me Unity actually has the better performance to graphics ratio among most recent games.
