Hum... To come back to the subject, here is my advice on how to optimize
paged terrains rendering. :)
- First open to the DatabasePager.cpp file and take a look at all the env
variables available.
- Now play with them. :) If you have a single core CPU with an ATI card, set
an high priority for

Hi Richard,
Way too little information to be able to know what is up with
performance, so lets start with a few questions to get the information
needed to guide you in the right direction:
What platform are you working on?
What hardware?
Did you compile a release build?
What performance did
lots of in depth best practice advice?
I didn't realize it was that complicated a question, I'm sorry. If
someone asked for some general performance tips for using OpenGL, I
could probably spout off about 10 or so cold. I didn't realize OSG was
so complicated that you needed a training

Robert,
I didn't give all those details because I'm looking for more of a
best practices type of advice. Just loading the terrain just
works, but is this the typical usage scenario for most users? What
are some of the common ways to speed up a terrain database created
with osgdem in this
Hi Richard,
You shouldn't have to do any performance tuning with VPB dataset, they
are supposed to built well balanced in the first place. If there is a
problem then its not a general problem but something very specific
about your system and the way you've set things up - from the little
stats

I'm loading a terrain set created with osgdem (.osga) via something
like this:
pTerrain = osgDB::readNodeFile(oahu-10.osga);
Easy as pie. However, for a really dense terrain, the performance is a
bit lack-luster. I wonder if everybody knows a trick that I haven't
discovered yet for
