I disagree. It can't be perfect (and support 100% of PC features available) but I'm impressed with how good it looks and how well it runs on my system. I have no shame calling is a superb PC version.
Never had a problem, never ran into a single crash.
Obviously, I only speak for myself. No PC version can be issues free for 100% of the PC gamers landscape.
Sure, but Ubisoft seem embarrassingly bad at PC releases given the amount of money and resources available to them. It's probably not going to change while Yves Guillemot is at the helm as he openly treats PC customers with contempt.
