My tests were one quad = 2 triangles. Triangles still won. I was suprised
to say the lease, but the numbers were there. Remember some cards and some
drivers take quads apart and turn them into 2 triangles. Also, the vertex
buffer in some cards can cache vertex information for a few vertices, so if
your triangles are sorted with adjacent edges you can get speed
improvements.

I'm quite sure about that. Question is if quads render slower or faster
than double amount of triangles. I've found triangle strip performance
to be best on the block, but for single triangles/quads it seems that
one quad is better than two triangles.
