One theory I've heard is that with vsynch off you end up with a bunch of 
junk in the pipeline, basically the undrawn remainder of the frame when 
it gets interrupted.

Yeah, I remember those days too. I remember always turning vsynch off, 
much like people perform religeous rituals. I don't remember it making 
any noticable difference though, even though my fps numbers were higher.
