Yes, but my bump map is *very* large. Much larger than I could make the
resolution
of the mesh without running out of memory i think.

Slower to render? Its definetly faster to parse!

Yes but its not limited to the resolution of  the mesh. And even if it is
limited to
the resoultion of the height field, that resolution is a lot higher than I
can
(practically) make the mesh. Still I know very little about this and could
be very
wrong. Please correct me if I am :)
