G’day all. I am currently updating my 737 sim from an FSX/Aerosoft to a P3Dv4/iFly setup. I have most of the MIP mapped and working as expected. However, l am having an issue with a ‘stuttering’ speed and altitude reading on the PFD. This in turn affects engine power where l get continuous N1 fluctuations. Data transfer with buttons and switches are virtually instantaneous (I.e. they react instantly when selected) and the scenery is as smooth as a baby’s backside. I have been ‘troubleshooting’ for the past three days without any resolution. To add confusion, if l project the 2D panel to my screen, the speed and altitude readings operate as expected but my PFD still stutters.

Can anyone offer a suggestion as where the problem may lie. 
Thanks in advance

Could be an accelerated graphics problem. How are you driving the pfd dispay? 

Found the issue late yesterday. It was conflicting software l thought had been removed (mate only removed the shortcut, not the program). Sim running much smoother now.

Thanks for the response in any case

cheers Steve
