Thanks guys for the answers! I guess it's OK to take a hit at the beginning if things run smoothly afterwards, so I don't think I need a incremental compilation.
Based on your answers I found a similar question here http://forum.openscenegraph.org/viewtopic.php?t=4997 So I tried this: osgViewer::Renderer* renderer = dynamic_cast<osgViewer::Renderer*>(viewer->getCamera()->getRenderer()); renderer->setCompileOnNextDraw(true); which is promising beacuse it creates exactly the same stall that I was seeing before. However, if I have hidden objects under a switch or if it's outside the frustum, I still see a recompilation triggered automatically once it is in the frustum and visible under the switch. So how to compile the _entire_ scene? /Per On 2 September 2014 14:21, Glenn Waldron <[email protected]> wrote: > Per, > If you don't want to pre-compile your GL objects, the > IncrementalCompileOperation might help too.
