With Performer2.0 you can download texture into the hardware texture memory
yourself if you want to. I use pfuDownloadTexList with PFUTEX_APPLY in my
draw process to download textures dynamically. PFUTEX_APPLY only downloads
it and doesn't show it as perfly does.

Second way as given as one of the performance optimization schemes is to
"pre-define and pre-load all textures through pfApplyTex() in pfConfigStage()
callback or (for multipipe applications to allow parallelism) in the
pfConfigPWin() callback".
