Existence ? 2004-01-25 - By Joel Blackwell

Untriangulated coplanar faces can cause problems in all sorts of
environments (rendering, games, etc), though TS can triangulate things
as it renders, saving you having to do it yourself. This may be why you
don't see any artifacts when rendering non triangulated objects. If you
want to try it off, just deactivate the trianglaute control under render
options.
Anyway, head here-

and download the triangulation example video, which explains the
difference between using SDS with both triangulated and untriangulated
faces. It might be of some help. Triangulation and SDS work fine
together, if you know how to handle it.
