Hi All,
Sorry if this is an old chestnut, but I got a question about the .osg file
format.
I've got a scene created, and I save the universe out as a .osg file. I've
passed no options through in the the call, so the file that's created appears
to have the textures that the scene uses actually

Still doesn't explain why I only saw it with an SMP kernel - is it a

Hi Benjamin,
Could you possibly repost the below text, but broken down into shorter
paragraphs as long paragraphs are really hard to follow. Try to keep
one major point per paragraph.
You are tackling a big topic in terms of performance optimization, so
its worth taking it bit by bit.
Robert.
Hi Pete,
Try using pbuffer rather than FBO, NVidia's Linux OpenGL drivers
handling of FBO'd cubemaps broke performance wise about six months
ago. Switch back to Pbuffer fixes the performance issue even though
it introduces a copy texture operation.
Unfortunately I haven't yet exposed an option t

Robert,
I just have sent a fix for heavier issue. New
Camera:DrawCalback::operator()( RenderInfo & ) needs to be exported in
Windows. Otherwise windows app using Camera::DrawCallbacks would not link.
