none of the renderers except snapshot does support
rendering of mapped textures in a VMD compatible way
or it is not (yet) implemented. this has been discussed
on this list a few times already.

your best shot at getting better image quality is to
switch to GLSL mode (in the Display menu), provided
you have a capable graphics card and a driver that
is not broken (which is rather rare. see other mails
to the list... :-( ).
