Thanks for the info! But how do I turn it off?

Only the wrl files use references, but they were not used for
OpenSceneGraph, because I clouldn't find a reader. That's why I
converted them to obj-files using 3DMax.
I also tested OpenSceneGraph with optimisations turned on and off and
the difference wasn't really big.
I used these lines for the optimisation:
<code>
// optimize the scene graph, remove redundant nodes and state etc.
osgUtil::Optimizer optimizer;
optimizer.optimize(xform);

Thanks, I will try these models first thing on monday and post the results.
Cheers,
