[GEM-dev] curve3d CPU usage

Hey all,

I'm trying to get slightly better resolution out of my curve3d objects,
so I'm using them in array.

Strange thing I'm seeing is that each curve3d rendered seems to use up
about 20% of my AMD64 CPU. (3200+, Nvidia N6600) (on linux) running 60fps.

Though I'm not manipulating the points at all, just connecting the
gemhead straight to the curve3d and thats it, 20%.

I'm aiming to use a grid of 4x3 curve3ds, but my test patch has only 4
and its already using up about 80% of my CPU without even sending new
control-point data.

Any ideas on how to make this object more optimized? I'd really like to
be able to use more than a few of these objects...

(no wonder my performance patch with a cube of 6 curve3d objects uses up
100% CPU of my 1.25Ghz g4 powerbook.)

Thanks all.
