Hello Chris,

Excuse me to come back on this question. But can you help me about  
width image size and drivers ? Do you know if there is optimization  
with the NVidia driver 180.44 and images with size multiple of 16 px  
in width ? If the answer is yes, i have to resize my images because i  
use 768 textures with different size at 4 fps (enough for me but if i  
can optimize, why not ;). (I use GeForce 9700M GTS on Ubuntu 9.04).
Thanx.
++

Jack
