Hey all,

I've been working on fixing a large MultiGen database using MultiGen
version 14.0. The database had, among other things, problems with
detail textures. I went through the entire database and cataloged
all textures used and selected an appropriate detail texture (where
necessary). Now, when I perfly the database on a RE system using
IRIX 6.2 and performer 2.0.2, and OpenGL my frame rate is about 1/5
of the performance than when no detail textures were used. I
expected a performance hit but really! This performance hit is even
in places where I wouldn't expect it -- when the eye point is far
enough away from the terrain so that the detail texture is not seen.
I can't find much useful info in the performer documentation. Is there
some adjustments I can make somewhere?

Any info is appreciated!
