Wouldn't be of any help for them, since my 4 years old PC is below min. requirements.
So, it plays smoothly (25-45 FPS) only above water. Also, I may tell, that people should think about upgrading to DX10, because, the game seems to be more stable and definitely MUCH better looking with it.
So I expect you'll be finding a spot mid-channel to stake out as your own?
