Do people even realize what bullshit this whole 3D gaming is this gen?

Do you all realize that the PS3 doesn't have the power to handle 3D? You need to render each frame twice, basically running at 120MhZ total, for the 3D that you usee to work. What did KZ2 work at? Oh yeah, about 30. Now imagine if it required twice the resources to render. More so because you'd need it in HD as well.

If you are lucky, you will get games that looks like the worst Wii games in 3D, if you are lucky.

No you still need to render each frame only once, because your displaying the exact same frame twice. You display 120 frames but only render 60 that you display twice offset from each other.

No, you are just wrong. You render each frame twice, you don't just display it. The 2nd frame has to give the perspective as it was rendered a few inches to the side of the previous one, as if you were looking through the other eye.

Basically, the game has to render the first frame for your right eye, and then render a whole new frame for your left that is offset by a few inches. They are distinctly different images and each one has to be rendered. No console has the power to do this on other than simple Wii graphics, hell even my PC can't handle 3D well and it puts the PS3 to shame in power.

In order to do 3D on a console videogame, one of 2 things need to happen.

1. Game needs to be built from the ground up with 3D in mind and optimized so that it runs at 30/60 frames per second in 2D and 60/120 frames per second in 3D.

2. Existing game needs to have the frame rate modified so that it is set to minimum 30 frames per eye. 60 fps games can be done in 3D with 30/30 per eye. Wipeout HD for example...

In any case, Vlad is right, frame rate needs to double and you need a monster machine to do 3D...console or PC. Also, a game can be done in 720p if they are 1080p to save some performance...but considering most PS3 games already run at 720p (or lower), that wont help.

Edit - I see what Icyedge was saying. While it may be true that PS3 may pull off some trickery like that where it renders the frame only once and then doubles it (the PS3 driver update is hinting at this actually)...this will provide a subpar 3D effect. that the same tech as the 2D to 3d tech which is included in Samsung and LG TVs. So lets hope thats not it...

But its also the same tech used by nvidia to transform 2D games to 3D, the result are good no? Since its the developer that will program it the result should be better than when its a software that does it, because they can adjust the offset ratio depending on the scene and whats going on, things that software have a hard time to do. Until now the playable demonstration receive good reviews so im pretty sure it will work well. Probably not as well as real 3D games on computer tho.
