Hi, The most common problem with performance is a poorly conditioned scene graph, so this is the place to look first rather assuming there is a problem in the core OSG that needs a major rewrite. The OSG is used very widely with plenty of people pushing it as hard if not harder than you are and still hitting a solid 60Hz.
Now an increase in cull time of 5ms with adding a single model is seriously out of keeping, so this really needs to be look at in isolation - what exactly is in the model? What update, cull and draw times do you get for each of these models? Robert.
