Hi Werner, Hopefully others will be able to chip in as I don't have a answer right now, it's certainly very odd. If it were a general problem then we'd seen lots of issue with it being reported.
With this level of slow down it's almost like your'e invoking a software renderer when running with 3.4.0. My next thought is that perhaps an OpenGL error is being invoked somehow. Are there any errors being reported to the console? What happens with the standard OSG example set? Does osgviewer run any differently with models you have on the two versions. Robert.
