The technical detail is that LDView requires the video card/video driver to
support the WGL_ARB_multisample OpenGL extension. The MX cards don't support
that. (I think this is because they only support supersample antialiasing.)
However, if the card's control panel allows you to set the FSAA mode used by
OpenGL cards, it might make the snapshots come out antialiased.

That sounds right to me (assuming edge lines are the look you want, I think it's
highly appropriate for the MOTM contest). Also, it's probably best to disable
the seam width option when edge lines are enabled. I would also suggest making
sure stud logos are enabled, with tri-linear filtered textures.

I'm honored.
As far as I know, the main things that would differentiate an image created by
LDView from one created by LDGLite are smooth-shaded curves and stud logos in
LDView's favor, and smooth patterns in LDGLite's favor (antialiased outlines of
patterns). The lighting may be a little different, too. On another technical
note, I think we have different polygon offset settings, which can make either
one or the other look better, depending on the scale and viewing angle.
