Greetings,
Sorry for the wall-of-text. I am working on a really thorny issue, and I want
to include as much information as possible.
I am not sure that this is necessarily an OSG-related bug, but I was wondering
if there is anyone here who can provide some insight anyway, because I can get

Hi Knarf,
what Silverlining do you use? the most vurrent ( 2.15) ?
What is your system? Especially your graphics hardware? Nvidia oder AMD?

Hi All,
I implemented a class that embeds an osg::Group. The real graphics for my

Hi,
Maybe the ReadNodeFileCallback can help you.
It is used by the DatabasePager, so you can manage what is done for each
readNodeFile call.
Or maybe making your own node node as PagedLOD which load the file only
when requested...
Or playing with UpdateCallback...
Sorry this is not a real

I have no idea I am afraid, I have seen the jumping as you describe.
One thing to try is when its jumping or the framerate is choppy, press m and
change the threading mode, does the choppiness go away?
It could be the stats are showing correct and there is something tying up
the GPU when

Sergey,
Thanks, that's been very helpful. I have some other questions though: suppose
you have a graph with camera C, a child of sibling cameras A B, e.g.
A - C
B - C
Will C be rendered twice? If so, how would one make C render first, then render
each of A, B with the output textures of C?
