Hi GuiYei,
The osgViewer doesn't have an OsgSceneHandler and their isn't an equivalent.
Perhaps you could provide a bit of information about what you were
doing with the OsgSceneHandler then we might be able to suggest how to
replace this code.
Robert.

Also try running osgviewer.exe loading your model. If you see a large

Hi GuiYe,
All the cull settings that you've being doing with SceneView in 1.2
can now be done directly with osg::Camera as it subclasses from

viewer.getCamera()-setComputeNearFarMode(..);

Try loading each of the 18 models separately and see which models decrease
your FPS the most. Then study those models closer to see the cause.
Press the 'S' key twice in osgviewer and look at how much time is spent
