Hi Fungus,
I also thought initially that vertex coordinates would not matter but
if the application
is lets say per fragment limited in this case larger triangles would
consume larger
percentage of the time as compared to smaller triangles so i had to
revise my
judgement.

In such cases vertex coordinates would also affect performance.


Well, that's true, but not likely in this example.
I really doubt it's the cause of his problem.

In science it often happens that scientists say, 'You know
that's a really good argument; my position is mistaken,'
and then they actually change their minds and you never
hear that old view from them again. They really do it.
It doesn't happen as often as it should, because scientists
are human and change is sometimes painful. But it happens
every day. I cannot recall the last time something like
that happened in politics or religion.
