I have a flight simulator variant of Perfly which utilizes pfpfb
routines to implement database paging. The database paging
implementation is working fine. There is however one related
problem.

We are wanting to preload all of the textures that are used in
our Performer Flight Binary database. We know these textures
beforehand, and create a pfList of textures which is then loaded
into Texture memory with the pfuDownloadTexList. We have found
that the pfpfb routines maintain their own list of pfTextures
found while loading the database. The pfTextures "downloaded"
to Texture memory are not being used, instead the pfpfb routines
are loading the pfTextures into Texture memory as they are
encountered, transitioning through the database.

Has anyone else dealt with this problem before? Can anyone offer
insight toward a solution to this problem?

This is my third posting (and rewording) of this question. If
there is a better place to pose this question, would somebody
please let me know!

Any help/guidance is appreciated.
