What causes tearing when panning around in MSFS

Hi guys,

I have a 2080ti and a 10700 cpu. When I pan around in MSFS i am getting tearing of the image. I have been fiddling with both my in-game settings and also in-sim but I don't know what setting I have changed to cause this. I don't remember seeing this when I first installed MSFS.

Can somebody point me in the right direction please?

Cheers
