I have no idea, but I do know that plib/ssg was very tight and clean and fast code. OSG is very feature rich, it has far more capabilities than plib/ssg, but features usually come with a price. I wouldn't be surprised if we take some amount of a frame rate hit moving to OSG. Hopefully we can find ways to optimize to minimize this problem, and perhaps there is something glaring we can find that will win a large amount of this performance loss back. Curt.
