Re: [osg-users] A Viewer question

Hi all, Don,

I'm still having the same problem. I'm running on P4 1.6, Windows 2000 SP4, NVIDIA GeForce FX5700. I've updated my card drivers, removed all of my code and left only this loop:

bool run()
{
    for(int loop=0;loop<36;loop++)
    {
        osg::ref_ptr<osg::Node> test=osgDB::readNodeFile("cessna.osg");
        osgProducer::Viewer viewer;
        viewer.setUpViewer(osgProducer::Viewer::STANDARD_SETTINGS);
        viewer.realize();
        while( !viewer.done() )
        {
            viewer.sync();
            viewer.update();
            viewer.frame();
        }
        viewer.sync();
    }
    return true;
}

..and when if loop ends (before exit) I have a memory usage ~25MB more than the first than the first while loop. I've noticed that OpenThreadsWin32.dll and Producer.dll are always in memory, although I call osgDB::Registry::instance()->closeAllLibraries().. If it isn't an OS memory problem, is there something I can do to shutdown the 2 dlls?? Is there a windows - graphic card configuration without this problem reported??

Thanks, Spyros.
