3D on PS3 is very limited

This is from Gizmodo, they are always anti Sony, trying to stir up crap. And this has been posted before in more detail. The quick fix on old games will require lower rez (WipeoutHD), yet some old games were tweaked easily to be 3d AND 1080 AND 120hz (60hz per eye) like StardustHD3D, and it came out in 2007! New games will be designed with 3d in the graphics engine, and one estimate I read was 3% extra computing time if they do it in a spu. Your not doubling the computation time, most of the calculating is done, textures loaded, physics, your just drawing the screen again at a different horizontal viewpoint. Relax, the games will look great, 3d is not just doubling your viewing pleasure, it's cubing it, and movies and nature documentaries in full 1080 3d will be amazing.

Why do people keep assuming the output is halved? Maybe I missed something but no one has mentioned halved at all. I am also well aware of just how this technology works, and while youd don't have to re-calculate the AI, physics, etc. You still have to draw all the polygons and shaders and other such stuff. As I mentioned before, games on the PS3 are already sliding by at 720p with barely reaching 60 FPS, if at all. Now add the fact that you have to draw the screen twice as fast, and imagine what will happen. Your Killzone 2, GoW3, etc. will never be in 3D this generation unless they slash the fidelity.
