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.

Thanx Chris, but the solution given by Iohannes seems to work
perfectly.
However, is it better for performance to give to an image a width
multiple of 16 in any cases or not ?
I use the last NVidia driver 180.44 on Ubuntu 9.04.

However, there is something very strange if it's about memory
because on my MacPro 2x2.66 GHz Dual-Core Intel Xeon, i have only
256 MB on the GPU and all works fine on it (only 2 fps but it is
not so slow).
The size of the images are between 127x108 and 72x123 pixels (so
the total size at 24bit is near 12 MB ! : 127x108x3x300/1048576 =
11.77 MB).
Most of the drivers have optimizations for images that are a
multiple of 16 in width, so maybe try using 128 pixel wide images
and see if that helps.
