I did not see "updateTimeStampOfObjectsInCacheWithExtenalReferences"
which does
the same.
So, why am I reloading textures? They are not referenced by the geometry?

You were right. It was a memory problem. I run out of texture memory.
I have added these lines to osgviewer.cpp :
osgDB::ReaderWriter::Options *options = new
osgDB::ReaderWriter::Options();
options->setObjectCacheHint(osgDB::ReaderWriter::Options::CACHE_ALL);
osgDB::Registry::instance()->setOptions(options);
It work well for the firsts loaded meshes.
But the DatabasePager, in the method "removeExpiredSubgraphs" calls :
osgDB::Registry::instance()->removeExpiredObjectsInCache(expiryTime);
My terrain is paged, so there are things in the cache that have been
loaded
a long time ago (like textures) and are remove from the cache.
I think the proper way to update the cache is to check the ref count
of the
objects. An entry can be removed if :
- it's ref count == 1 (only the cache references it)
- timestamp < expiryTime

I can only have a stab in the dark, its your dataset and your machine.
My terrain tiles are not so big. The biggest file: 278Ko (ive format).
I will check the number of faces.
Do you know how to disable display lists? I want to use immediate mode
so no data is uploaded to the GPU memory.
drawable->setUseDisplayList(false);
Or use the osgUtil::GLObjectsVisitor which can run through your whole
scene graph set various OpenGL object releated behaviors.
The OSG by default enables display lists, while Performer doesn't.
Also try sourcing up to date drivers. ATI drivers have been
historically very poor at OpenGL.
