I've bee experiencing momentary frame drops when I rotate my camera in my scene. After look at the osg code, I noticed that many of the opengl objects are created during runtime and not when the model is loaded. For example, opengl texture objects are only created when the Texture2d::apply() is traversed. A drawable display lists is only created when its Drawable::drawImplementation() is called.
I suspect that, in case, these runtime object creations are the cause of my momentory frame drops. Is there a way to precreate all open objects located define in a scene graph? That way I can confirm my suspicion. One way would be to have a VERY big camera frustum that encloses the entire scene and then renders one frame, but that seems a little *hacked* to me. I am trying to look for an alternative and better way to do that.
