What I expected to happen.
No stutter when using the plugin on G3000/5000 airplanes every second.
What actually happened
When using the plugin in airplanes with the G3000/5000 like the TBM or Longitude there is a stutter every 1 second. I can link it to the aircraft position update on the charts.
I have a pretty high-end PC and GPU and I only have this problem when I use the Navigraph plugin on a G3000/5000 or the in-flight panel.
When I uninstall the plugin, the stutter goes away.
