Current SVN, DrawThreadPerContext (the default) with osgviewer, SingleThreaded in my own application (anything else breaks Replicant, but that's another issue). > 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. SingleThreaded seems to work, DrawThreadPerContext hangs often, CullDrawThreadPerContext didn't hang on me yet, CullThreadPerCameraDrawThreadPerContext hanged. However, as this seems to be timing-sensitive, take this test with a grain of salt. > > > Do the hangs always happen at start up? Or any point during rendering? No, not always at startup. It usually happens after I move the mouse or rotate the object. Sometimes it works for 10-15 seconds and then it the motions gets jerky, normal again and the usually hangs. > 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. I can send you the ones I have got from Joan off-list, I hope she is OK with that.
