I got an early copy (snuck a sale in during my shift at work when it was behind the desk ) and I dunno what this guy is talking about but the graphics on high detail look great. The water reflects realistically, you can see wild life in the environment such as fish swimming, birds flying etc. and the bump mapping looks good to. It's nothing revolutionary and I give it 2 weeks before I uninstall and forget about it but it's good none the less. Also, why are you saying that it's slow? If you manage to find a server with a decent amount of people the game speed is actually well balanced.
7/10 from me. It's enjoyable but not spectacular.
