I'm having problems when using more than 15 or so cliptextures
(all 2048x2048, clip size 512) in one scene. For example, 12 cliptextures
works fine, when I add the thirteenth (just pfdLoadClipTexture() it - not
even use it), performance drops from say, 30fps to about 2fps and there's
some garbage in the displayed textures.

We're trying to make cliptexture movies using a modified clipfly (I've
also experimented with Performer/src/pguide/libpfutil/movie.c and
Performer/src/pguide/libpf/virtcliptex.c)

Onyx2 IR w/ 2 64MB RMs pf2.2

Thanks,

Steve
