GTN in VC very laggy on Just Flight Turbo Arrow

[NickSilver]

So I picked up the TDS GTN since it now has VC integration and uses the garmin trainer.....but I am having a bit of an issue with the VC version being very laggy to inputs. IF I pop the screen out as a window it works perfectly but using it in the VC is just mind numbingly slow.

I have panel refresh set to high in sim, and I don't see any other settings that I know of to make the UI snappier. Any suggestions? This is the only GTN unit I have in the community folder.
