If it's an MMX problem, then it is an Intel MMX problem.. since my K6 hums
along fine with squake any number of times I play.

Even though I'd suspect that the game play would be noticably slower
with the Pentium memcpy, it's not.

So, I kinda sorta doubt it, unless I'm over-ruled by others who have
the same problem.

Has anyone given some thought to abusing the MMX codes for non-video,
non-audio uses? Might be worthwhile, although I honestly haven't
browsed the MMX spec sheet yet.

Which is worse: ignorance or apathy?  Who knows?  Who cares?
