I have a Nvidia card (the 2047MB GTX560 to be exact) and decided to have a bit of fun and try Obduction with the 3D Vision driver and use the old-fashioned blue/red cardboard glasses (AKA: Anaglyph 3D). Overall the game looks pretty cool in that type of 3D and is mostly playable (though the red shades in the game are muted by the red filter and the overall color is a bit wonky).
There was one interesting thing I did observe that could be consideded spoilerish for future Oculus Rift users:
When viewing a swap in a regular 2D game, it looks like a ton of colored lights swirling around. Viewing the same in 3D though, and I can still see an impression of the swapper machine through the whole swapping process. It's hard to explain but reminds me of thoes Magic Eye pictures where an image pops out of a jumbled background.
If you have the chance to do this yourself, check it out.
