I don’t know, but I certainly can’t recall a better-looking one right now.
Again, click on the picture to see it in full size (the thumbnail doesn’t do it justice), and then, because your browser will probably scale it to fit in the window, click on it again.
For info about the game, the hardware, and the settings the game is running under, please see this post.
EDIT: OK, I don’t have the game, but, from a screenshot, Crysis’s water looks even better than this.
