Doh. I was under the impression (for some reason) that Quake used fixed point emulation rather than the FPU. My bad. :)
The reason I asked was that I was curious whether I had some hardware wierdness going on, or there was a patch conflict. No big deal, I just wondered about it. :)
Regards and thanks to all.
