It also depends on what software you were using to generate MIDI clocks.
There are lots of ways to setup a timer for sending clocks, some are
more tolerant of what's going on in the system than others.  If you  
were using
a commercial product that's been around for awhile I would expect them
to do it correctly, but not everything does it the same way.

The receiving devices should also be doing some "smoothing" or averaging
of the distance between clocks since MIDI clocks are notoriously  
jittery.
Some devices are better at this than others.

Again it sounds like the video adapter causing problems.  They aren't  
always
available on a laptop but I recommend that people get a mid-range  
"gaming"
video card with at least 256MB dedicated memory, especially if you're  
using
a hog like Vista.
