The extra texture bitplanes will be used automatically; they allow
more textures to be stored in the graphics bitplanes, so the GL won't
have to swap textures from main memory as often.

The multibuffer option also gives you accumulation buffer capabilities
(motion blur, full scene anti-aliasing, and other interesting stuff);
see the acbuf(3G) manual page for more information.
