I looked through some older messages, and found a little more info on 3dturbo.
3dturbo is similar to optimize, but also imbeds an optimized model inside the
more detailed model. It also supposively hides backfaces, so that the
on-screen redraw time is less. Not sure from what view the backfaces are
hidden though. If you have more questions on it, it would be good to leave a
message in the IPAS Usage section addressed to all. Someone who uses the
product could give you a better description of it.
