Unfortuanately the first things I switch off in any game is motion blur and depth of field, so the image above doesn't have them enabled.
I have never seen this on any moving vehicle, or at least it's not noticable if it does exist, just the GSX personnel on the ramp.
Don't get me wrong I am not blaming GSX, just that it has become very apparent when using it.
I'll put this issue on the back burner right now, and see if it changes in the future, either with a MSFS or gpu driver update perhaps.
Cheers
