[racket] big-bang is slow to render on screen?

Thanks for the help.
Actually, I'm using the "nouveau" drivers as the nvidia ones apparently
don't like my screen and go on strike (just tested again, they still don't
work).

I have rebooted several times since yesterday, and the behavior of the
program is still the same, so it's probably not cache.
