What 3D solution only requires 4% more power? And what 3D solution are you using to game at 1080p?
Screen-space reprojection 3D, also known as single camera Z-buffer based 3D, many gamers call it "fake" 3D.
It's a very simple solution and elegant from a programmer's point of view.
The problem : it produces occlusion artefacts, so the developers need to keep the separation at a minimum and it makes games look very flat. Crysis 2 and 3 use this technique.
Some people like the compromise, but I can't stand it.
I bought Crysis 2 and was deeply disappointed by the results. When Crysis 3 came out, I just looked at a 3D screenshot made by someone else and immediately noticed the exact same problems, so I didn't buy it.
The Tridef drivers also have an option to use this mode instead of doing a full dual-camera rendering, I never use it because I can't stand the artefacts.
It's possible to reduce the effects and be able to use this technique propely, but it requires deep integration in the game. Until now, the only time i've seen this done right was in a console demo of Batman Arkam City at a trade show (TrioviZ booth) but the PC game didn't use this technique, it used the normal Nvidia 3D Vision instead, so I was never able to study it propely.
