When cross a sim board AV still jitter a little, in the Main grid. One of my AVs has flapping wings and the wings to wrap around me when crossing sim boarders. But the preview it does seem better. They only jetter a little but quickly but things do return back to normal within a frame or two.
It almost appears as if there is a 16 meter hand off between sim boarders. When I have another viewer looking at my flapping bat AV, it will jitter at one position then when he turn around and flys the other direction across the boarder it jitter at another position about 16meter apart. So 8 meters on either side of the board. Or maybe it is about a 1 second time to hand off
