I had some weird unexplained stutters while i was preparing H-Jet for take off  and after many tests and research i found the main cause.

When i start to import cruise & ILS final approach altitudes on flight-plan, aircraft starts to stutter even on high fps ( 60-70s). I used MSFS Developer mode fps preview and i saw those spikes on Main thread/CoherentGTUIThread and Manipulators when this happen.

In general Aircraft performance is amazing and smooth with out any issue until i  add the final cruise & descent altitudes for vnav calculation. 

Could someone confirm if its a bug? 

thanks

You might have better response if you posted this on the devs discord channel.

Pretty sure your issue is with the "far from perfect" G3000.  Until further development and improvements to the avionics, these type of problems will probably occur.

will check also on Longitude tonight. As i remember i never had any issue 

In my case I had to delete the STAR and that brought fps back to normal.
