HW texture memory is allocated by the OS upon a pfApplyTex().
This probably first happens when you do a pfuDownloadTexList()
after reading in your database.
When does the freeze happen? In the loader before pfuDownloadTexList()
is called or after?
If you think that textures have been downloaded, you can
run osview and see if we are hung in the kernel or in user code.
