Jim is right about the ghosting and the monitor. A friend of mine has ghosting in his games in 3d where in the same games I don't. But then again he didn't pay what I did for my monitor. I have the Alienware AW2310 3D. Smooth as silk and so far no ghosting. I'll check and see how much if any ghosting I get with the aquarium when I go back to the room.
i've got the exact same monitor as you, which certainly wasnt cheap lol but i am getting the ghosting which is odd. i am using nvidia 3 vision, i dont get the ghosting unless i increase the depth, have you tried increasing the depth on your 3d setup?
thanks for the replies guys and i'll try and adjust the background to a more neutral colour to test!
