I found your link on the Unity WIP forum and decided to give the game a go.  Unfortunately, I was not able to see too far because I was getting strange white patches from the terrain: http://imgur.com/yElE67o  (otherwise framerate and the looks is fine).
I'm using version 0.5.5 of the client and have an integrated Intel HD family video card.  I'm happy to provide any other information if I can.
I don't think this is the case of my card being unable to handle the game: I've played 3D Unity games before (including my own) and modern titles without seeing this behavior before.
