Yes.

I am resetting it. I am pretty sure this code is OK - when I measure with
a stopwatch, I get the same timing.

Good advice, I will try it!

I have no problem giving you a copy of the code, but it is not in a state
suited for distribution and pretty embarrising. If you want to have a
look, you can download 
http://www.challenge.dk/~madsdyd/3dse.20000407.tgz (200 KB)

It needs a working GL/GLU (preferable accelerated) and a linux system. It
will try to use /dev/dsp for sound. Most of the display stuff is in
display.c.

Mind you, the most (90%) of that code was hacked together from 02 AM to 1
PM on last sunday morning (20000402) after I and a friend had been to a
party... It is my first serious try on a game and I am currently rewriting
it, which is why I am offering you the last stable version :-) A lot of
stuff is broken, but the only thing I can't easily explain is the weird
drop in framerate.

Oh, hit c to try the framerate out (IIRC) - otherwise it is in keyboard.c

Thanks,

Mads

Oh well, all operating systems crash constantly right? This is normal, right? 
It has to be, Microsoft couldn't be so popular if their OS was so bad, could 
they?	   
  Yes they could, and they are. And if you fail to realize it, it's your own 
damn fault.
