The blogpost contains some details on how SSHD was optimized for 3D, but if you want those follow the link!

3D certainly has a bright future ahead and we are happy that we had a chance to develop the first 3D PS3game that runs 720p resolution in 60fps for both eyes, meaning that we are actually having 3D SSHD running in 120fps! The improvements we did for our engine are also benefiting the gamers of 2D version as well. To summarize, the 3D version includes:

• 3D mode of the game running 720p at 120fps (60fps per eye)
• 2D mode of split screen co-op mode updated from 30fps to 60fps
• 4x antialiasing support in 720p and native 1920×1080p support in 2D mode

The 3D update is free to all existing SSHD gamers enhancing also the 2D mode, so don’t forget to update your game even though you haven’t got your 3D television (yet)!

Those are some sweet upgrades!

cool, now i just need that 3d tv. think i will wait till  black friday to get one.

so this means it's running at 60fps 1080p in 2D

and 30fps 720p in 3D?

@ leo-j

The ways you can play it are this:

2D, 720p, 60 FPS, 4xMSAA

2D, 1080p, 60 FPS, ?xMSAA

2D splitscreen, 720p, 60 FPS, ?xMSAA

3D, 720p, 120 FPS (60 FPS per eye), ?xMSAA

I don't know what antialiasing is used for the modes outside of normal 720p, hence the questionmark.

I think there's no AA unless mentioned.

Cool...may as well upgrade the 2D version if they tweeked the game for 3D
