Dear John,

Thanks for answering so fast.

The driver version seems to be the most recent (see joined snapshot...sorry
it is in french!). Anyway, I cannot change it because it's used by our
informatic team for distant help on our computer.

Here is the message I got when I loaded the DX card :

Joined I add (only to you, not to the list!) two screenshots of what
appears on VMD, one on windows (admire the nice zebra!!!) and the other one
on Linux through VNC (it is 1.8.3 version on linux).

Thanks in advance for help!

Hi,
  It sounds to me like there's something amiss with your video driver.
The startup messages VMD is printing indicate that you have at least got
minimal 3-D texturing support, though the max texture dimension is small.
That test version of VMD you're using has automatic texture downsampling
code so it should be attempting to squeeze the texture into the 128^3 limit
of your video card, even if your DX map is much larger. GLSL doesn't play
a factor in the specific problem you're having. Can you verify that you've
got the most recent video driver for your machine? Please double check
that and get back to me. How big is the DX map you're loading? Can you
email me the messages that VMD prints in the console when you load it?
