Since buying Poser a year ago, I've just been using the Main camera to look around my scenes because it's the only one that runs smooth as silk no matter how many objects are loaded.

I just bought a new 1 GB Geforce GTX 560 Ti in the hope that it would improve the OpenGL performance of the Preview window, but every other camera except the Main still behave like a slide-show when I load one of my projects.  I re-installed Poser, but that didn't help.  I installed the latest drivers from nVidia - v275.33 - right after I installed the new card.

Is there anything else I can do to smooth out those other cameras?
