Depends on which 3Dfx card you have - but I'm guessing from the
question that you have either Voodoo-1 or Voodoo-2.

If that's the case then you need to set the shell variable 'MESA_GLX_FX'
to 'windowed' as in:

BASH:

    export MESA_GLX_FX=windowed

tcsh:

    setenv MESA_GLX_FX windowed

This is nowhere near as fast as full-screen mode - but a lot faster
than software rendering.  If you have a Voodoo-1/2 card then that's
as good as it gets because the hardware is physically incapable of
rendering into a window and Mesa has to copy the image out of
the 3Dfx card's frame buffer and into the 2D graphics card...which
takes something like a tenth of a second for most "reasonable"
hardware setups.

If you have a Banshee or a Voodoo-3 then rendering into a window
should be fast.
