The Truth About 3D On Xbox 360

Theres only a single major title that Sony has which will give them a good implementation of 3D at present. That title is Gran Turismo 5. Currently the game renders at 1280 by 1080 with 2x MSAA so if it can render at 1280 by 720 with 4x MSAA then they can probably also render at 1280 by 1440 to give an effective 1280 by 720 @ 60 FPS 3D. It can also be scaled to 2 or 4 consoles to yield a faster framerate and higher resolution output. People who don't like racing games will not get much benefit from PS3 3D because outside of this one title the games run at 720P and 30FPS which isn't sufficient to really do a good 3D implementation. I believe this is the reason for GT5's delay.

There we go...someone that know what they are talking about.

If they do 3D on GT5 on a single console, they would have to cut down the framerate per eye down to 30. I don't know if that would go over too well with the core GT gamers. I don't believe they can do 120 frames per second to pull off the 60 that is needed per eye to keep the same experience as when playing in 2D. I don't think they will bother with the checkerbaord pattern to make the res 1280x720@60 fps x2  like you said unless the game has native 3D support.

Scaling it to 2 consoles is probably the way they will go since they are supporting mutiple display support with multiple ps3s. In either case, there will be a trde-off.

Real racing fans demand 60FPS. Theres a reason why all major racing games run at this frame-rate and the people who would get 3D are the people who would notice 30FPS. Its the only reasonable explanation given the delays and the naturally higher resolution and frame-rate this game enjoys that they are making this title a 3D native. Theres no point in doing less than that as with this game in 3D the audience still demands 60FPS per eye!

The PS3 is notoriously fillrate limited, so taking it back from 2xMSAA to 0xMSAA or implementing some other AA method would give them back the fillrate they need to run the game with a checkboard pattern or similar implementation. The trade off is resolution/AA instead of frame-rate.
