the way the nvidia glasses work, the driver actually renders twice, once from a point of view slightly to the right, and once from slightly to the left. (since it has detailed 3d structures of everything and is responsible for rendering in the first place, that comes out right). You need a 120fps monitor too. And the glasses.
Anyways the problem with certain games have to with mixing of 2d and 3d mostly.
For example, if they put a name tag above a person head in 2d, aka, at screen level, and then you use the nvidia driver to do a 3d render for the glasses, you will see a person standing 5 feet ahead of you, with his name floating near YOUR head, not hear HIS head. If you were to relocate it to be above his head, than you will take slightly more effort to render it, or maybe program, but it will hover above his head instead of in your face.
So for elemental, it means having the cursor be a 3d object on ground level, instead of having it as a 2d overlay at camera level (aka, floating in the air above the ground). From what i read, this is actually a technology that works really well with FPS top down games.
