As another little test could you try: osgviewer cow.osg --stereo QUAD_BUFFER --SingleThreaded I don't expect this to fix anything but it's worth turning every stone we can to see if we can get a better picture of the problem. > Then we can say that should be a problem of Drivers or Hardware ? I think it's most likely a OpenGL driver problem. For the applications that are working it would be worth finding out whether they are Direct3D or OpenGL based. There will be other OSG users using quad buffer stereo under Windows so I'm surprised others haven't chirped up with a report of success or failure, it might be that they haven't spotted this thread, or don't currently have access to hardware to check. In the past users have reported success with quad buffer stereo under Windows so I believe there isn't a deep seated problem - it should work given fully working drivers. Given that a driver problem is the most likely issue I'd suggest looking at availability of new or older drivers for your card, and also check the NVidia forum and support to see if the issue has been seen with other OpenGL applictions.
