not really, it works properly. It just there are quite a few animation bugs, freerun control oddities, graphics such as object pop-in delay but nothing game breaking. Bare in mind, AC3 is not a rehash version of AC2/ACB/ACR, the team need to build most of the stuff up just in 1 year. However, if you dont like graphics for the consoles then PC is the only one to go, cos a lot of ppl complain about low FPS, and some huge openfield-combat may ended up to 20fps

30fps is the standard for consoles, considering that those large scale battles are over 20-30 units fighting at the same time with over 100 units in the sector for a lost of 10fps, generally i think its kinda impossible for most machines.
