Aircraft performance fall off with Win 7? last call for explanation

[Pugo3]

Thanks, I do not presently have XP available for such a comparison, but appreciate the suggestion.

As to joy stick calibration, I use the same CH Products joystick/rudder pedals as with my old set up [actually a warranty replacement-refurb of each type] with my Win 7. I never fussed much if at all with varying numerical values, just the standard CHP calibration.
