My system specs are fine here i5-4670k, 7770 ghz edition card. I have downloaded over 30 gig worth of patches. Game still lags, crashes, image corrupts, locks up, etc to where the game is pretty much considered unplayable still. It isn't your hardware that's the problem, it's the game itself.
They did a really, really poor job converting this game to the PC. I wish I had my money back as I have since uninstalled it due to it being a waste of hd space that I can't play.
