What threading model is being used? Which version of the OSG? Try forcing different threading models by using the OSG_THREADING env var, or setting it on the command line. See osgviewer --help and osgviewer --help-env for details. > If I do the same with osgproducerviewer, everything works and I am > getting decent frame rates even - few hundreds FPS, even up to 1000 > sometimes on my two 6800GS.

If you could provide a datasets then I could try it out on my system. I have a dual core Althon system and a new quad core Intel system, both right now just have a single card in but I can swap things around.
