Hi All,
I'd like to say thanks to the mailing list, for the support you gave me!
However, I'm fnished with the performance tests for now. All I needed
to know, was if the performance is comparable to OSG, and I'm totally
satisfied.
We (my Workgroup in the University of Cologne) will continue usin

Hi,
I updated my OpenSG last Wednesday and recompiled everything, before
running the same tests again.
Here are the results: http://vis.uni-koeln.de/FrameTests/Test5.htm
The obj files load much faster now, and the performance is as good as
it was before.
The Machine I am running the test on is

Hi,
I just did some tests on OpenSG and OpenSceneGraph to find out which
better suits my needs (Performance) So I wrote some little testing

again.

on a side note (perhaps you already know this): if you use endl to end a
