Hi Frank, The OSG compiles and VBO, texture objects and display lists on viewer.realize() using the osgUtil::GLObjectsVisitor mentioned by Jason. If you are assigning scene graphs to the viewer after realize the you may need to compile the objects explictly, either all together or incrementally - there is the osgUtil::IncrementalCompileOperator for this task, this class is designed to load balance to avoid frame breaks.
