Hi Andreas, yes, same problem. I have not more than 6 fps and yes I use the Debug libs of OpenSG. Plus - please don't laugh - my graphics card is a Intel(R) 82865G Graphics Controller (onboard, I guess). Well, if it's just a matter of hardware power, I would be satisfied, cause this can be changed.
