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.

Martin
