For what it's worth, 3d clouds seem to run reasonably fast by themselves,
but if you have 3d clouds + these new shader effects (or existing effects
like rain/snow) then my frame rates come grinding to nearly a halt.
Switching to 2d clouds with these new shader effects puts me back up to
running fast again. Also 3d clouds + drawing to multiple cameras/windows is
another thing that seems to bring the frame rates down substantially.
