We used to do this back when our application was in Performer, but we only had about 100 models then. Now we have thousands of possible models so it's unfortunately not an option.

What they did to avoid this they preloaded the models at the very beginning to let OpenGL compile objects and then used in the scene. Maybe you can do the same way Nick On Tue, Sep 2, 2014 at 2:03 PM, Cary, Karl A. <karl.a.c...@leidos.com> wrote: We have been having the same issue and haven't found a solution yet either, though it hasn't been our main priority yet.

There are range of things that can cause compilation to be slow, I haven't to head off line right now so will have to leave you with that hint... Robert.

I wonder how to minimize this effect. Clues: -Once the model has been displayed there is no more hiccup. -Differerent models produce different hiccup delays (consistently) -Hiccup problem does not scale with .ive size or nr of polygons -In bad cases I can see the osgstats cull part go to zero for about 1 sec. -Using ProxyNode makes no difference. Suggestions? Some caching options I can try? Anything nasty to look for in the .ive models? (Most are 3DS format made by 3rd party, converted with osgconv, sorry I can't share them) I'm using OSG 3.01, compositeviewer, linux, Nvidia (different cards, same problem.)
