Yes, actually, there is. The difference is slight, but definitely seems
to be there. I was going to mention that, but wanted to get a larger
sample size first. Here's what I have so far:

rand		frequency	avg. of avg. fps	std. deviation
1425745073	2		63.983518		0.451851
1919451183	28		64.612598		0.278567
2051811764	9		64.534478		0.207600
560406543	11		64.205582		0.225971

Obviously, the data for the first row is shaky because there aren't
enough samples. The difference between the second row and the forth row
looks significant, though.

I'll run the tests overnight and see what happens. Incidentally, bug
#1432 (ut2004 never quits) makes automated benchmarking a bit annoying.
I've had to do it like this:
for (( i=1 ; i <= $num ; ++i )) ; do
                               utbenchmark &
  sleep 50
  killall -SIGINT ut2004-bin
If somebody know a better way, please tell me. :)

I mentioned in the last email that it was a one-minute test. I was mixed
up, actually. The ut2004 command has -seconds=77, and it runs the game
for about 36 seconds (excluding loading time).
