I would say that's not totally outrageous for your render time. You have
some pretty complex CSG going on there. I'm guessing that you've subtracted
a torus from your text to get the curved effect on the surface of the wheel.
If this is correct, then that's an even more complicated calculation. Also,
it depends on your AA settings. Finally, check for subtraction vs. merge
settings on your CSG's. You might be able to speed things up a bit.
