MoSlo tends to give "jerky slowdown".

I mentioned that on a forum once, and then the author of moslo came out of nowehre and posted like "prove me wrong" or "don't misinform my product" or so.

try another slowdown program

I'd say it won't matter much, since the slowdown needed for most "finicky" games is too big to get smooth results.
Almost all slowdown utilities use the same method, which is forcing the CPU into delay loops at certain intervals, the only thing you can vary is the length of the loop and the frequency of the intervals. This allows for a certain fine tuning, but it won't make the "jerks" disappear. There are other utilities taking advantage of the power-saving features of certain CPUs, these obviously work much better, but your hardware has to be supported.

However, the K6 and Athlon(XP) range of CPUs have one big advantage: Their multipliers are open or can easily be unlocked. Given a late CPU model and a decent mainboard, you get a range of 100 - 500 MHz for the K6 and 500 - 2000 MHz for the Athlon.

Athlon isn't unlocked unless you buy a mobile version of it or do the mod to the L1 bridges...
