Hi, Robert This morning, i've checked your suggestion: using osgviewer cow.osg --stereo QUAD_BUFFER
It was same...the problem is still there...sometimes, I got frozen screen... Then we can say that should be a problem of Drivers or Hardware ? Thanks alot~ Cheers, Nan ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39927#39927 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
