Consistent stutter / memory leak

[MNorm757]

Getting a consistent stutter and framerate drop every 3 seconds with the YS-11 in MSFS2020. 

Have tested with all default liveries (with and without gps) at multiple airports and with a clean Community folder.  Have also recreated exact scenarios with 7 other payware aircraft and the symptoms are only with the YS-11. I've also tested this in both DX11 and DX12 with multiple V-sync and Freesync settings.  Regardless of any settings, background programs, NVidia driver, DLSS version, sceneries, etc. the fps drop and stutter/judder occurs almost exactly every 3 seconds.  Have deleted and reinstalled the YS-11 twice and the symptom persists.

This issue has also been reported on other forums by  users on XBOX and PC (I use PC).

Same for me

confirm, stutter every 2 or 3 second in every scenario, livery, gps selection or graphic option.

+1
all other aircraft runs smoothly but YM-11 also stutter constantly every 3 secs

Unfortunately, since inibuilds seems to be moving on to other projects without an update, I'll be sticking this bird back in the hangar.
