ATI doesn't do display lists at all well, change the DatabasePager to
use vertex arrays to see if that helps. Run osgviewer --help-env to
list the env vars that you can use to enable the use of vertex arrays.
We have the same issue on ATI cards. The paging problem never really got
fixed in

It won't make any real difference. Things should scale comfortable to

In the first case, you have 6 levels of detail, in the second you have 8.
The presence of additional levels of detail will not affect the rendering
performance of the existing 6
Q2: What are the parameters can I tweak in an OSG application to
tweak how the program runs?
Well there are hundreds of classes with dozens of methods in each...
so a massive set of options you can tweak. First thing is to
figure out what the actual performance problem is then to

I happened to be looking at that today. I noticed that the
call in Renderer.cpp (2.2 and trunk):
databasePager-compileGLObjects
Always uses 0.004 for available time. So, unless you roll
your own Viewer, your stuck with this time. Also, it doesn't
seem that variables:

I don't have the 2.2 book to compare against, so I apoligize
if I get something wrong.
Sorry, I must've misread your post. I tried to direct you to the env var ref
for more controls, and I thought your reply to my post was suggesting that
you had read it and found ti to be in error.

First, thank you to everyone for their work putting OSG
and VPB, this is really an amazing piece of software.
Q1: Is there any advantage to having a single large osga
model built from say a 16kx16k input or having lots of
smaller 4kx4k tiled sections in separate files?
Q2: Will rebuilding the
