Well, I can't comment on Genius 5 as I don't have it, but I have noticed
a similiar (80% difference on the average) performance hit when running
Mchess 7.01 in DOS as opposed to Win95. I can assure that it is not due
to any TSRs or other software running in the background as if I call up
the special Rebel9 windows shortcut it runs almost identically in speed
as when run in DOS. I have no explanation for it but I can give you test
suite results with the resource monitor's results as well for your
examination.
