I just changed my FSX from using the FSX controllers to having FSUIPC run all of them in anticipation of changing to Win 8.1 in the future.  Although a long time user of both FSX and FSUIPC, I always used FSX to operate my yoke, pedals and throttle.  I was struck by the massive reduction in frame rates when I tried a flight this morning with the Airbus X and my usual programs.  It was a slideshow in the mid teens before I got above the weather.  Normally it would be in the 30 and 40's range during takeoff and going up to cruise altitude. 

 

I did not make any other changes and this was totally unexpected.  I would like those to chime in who have the same or different experience so I can determine if something else may be causing this than just changing how my controllers are run.

I dont have that plane but I think i read that you are not supposed to use FSUIPC to set up assignments or calibrations with it as it has its own tool.

 

You could check the Aerosoft forums to check or see if it mentions that in the docs that come with it.

 

Someone here who owns it can probable give more info, just speaking what I remember reading somewhere.

I use fsuip and a lua script for throttles with it with no problems.
