I'm talking about 3D graphics on both screens at once. Every thing on the market seems to have 2d on one screen and 3d on the other.
[quote name='basketkase543']Ever since the DS was announced, Nintendo said that it was made to have 3-d graphics on only on screen at a time (it didn't matter which screen).[/QUOTE]
Not true. Either screen can be in either mode at any time. Both can have 2D, or one can be 2D with the other in 3D, or both can be running in 3D.

Technically, the DS can only render 3D to one screen at a time. However, it can alternate rendering frames to one screen or the other. Essentially, if the 3D engine can run at 60 frames, they can split that rendering power between the two screens and have each run 3D at 30fps by having the other screen "hold" its image while the other is being rendered. It's not effecient, but it works.
