ch yoke / pedals

One of the problems is that FSUIPC is all jittery on the push/pull (elevator) action of the yoke.  Yet, it does not jitter in ch control manager calibrate or test windows.  The aileron is fine in FSUIPC and ch control manager.  I don't remember having this problem with my Win 7 / FSX box.

Pete Dowson would be better equipped to respond to this but as I understand it, FSUIPC deals with raw inputs and is more sensitive to fluctuations. IIRC there is a setting to eliminate spiking. For many years now I have never had a problem with controllers that was related to FSUIPC whereas I read all the time of problems with Windows, CH CM etc. 

Many years ago I just got tired of the rat race and bit the bullet and learned how to properly set up FSUIPC. Until that time, I was fighting the same battles as you.
