Thanks again Robert for these informations. I've made some tests and everything fails :
- I've tweaked osg::Object to have all the objects in DYNAMIC, it still crash. - I've installed the NVIDIA beta drivers, it doesn't change anything. - I've tested the CullDrawThreadPerContext mode, still the same crash. - I've tested with a simple model and not my whole application. It only works on SingleThreaded mode, but the frame drop in this mode is not acceptable. :/ I'll continue to investigate on the subject but I start to desesperate. My application uses a CompositeViewer with different osgViewer::View for each window, I'll try different setups to see if it still crash.
