Hello,

I am using Performer 1.2 on a RE with 16Mb texture memory.
I have several different terrain databases that I can load
that use the full 16Mb of texture. Most of these applications
run fine (30 frames/sec), but yesterday I discovered one
that is loading texture every frame (2 frames/sec).

While running, I turn on the statistics (a la perfly demo)
and it tells me that it is has six textures and is loading
12 textures for just under 32Mb every frame. Having
constructed this image, I know that each of the six textures
is 1M pixels, and the texture loading at run time says that
total texture memory used is a few bytes less than the 16Mb
limit. What is going on here?

The only thing different about this database is that I have
some terrain that is lighted (has normals), but not textured
(nor has texcoords).

Thanks,
Mark G. Yarbrough
