The only game i've noticed actually giving you a wider viewport on the game in 3d is PUzzle and Dragons Z. It's not just things that you can see sorta, it shows more of the world the higher the level of 3d is, and that's strange to me. So clearly they're always rendering it I doubt the game is that demanding since only the game world itself is 3d and allof the characters are just sprites but I found it odd that you can see more in 3d than you can in 2d. I am tempted to try to use ntr and get a screenshot of it and see what the framebuffer shows.
