I was doing some field gunning and noticed that every time someone flew in or out through d2.0, the plane would halt in midair, twirl around a bit, then warp off in the direction they were flying. The pause was almost always about 1 to 2 seconds, very very noticeable. Everyone would be smooth inside 2, smooth outside 2, but right at 2.0 they'd pause or warp a bit, hang in midair and twirl around, then warp back to wherever they really were.
It's like there's some goofy delay in the smoothing transition between the different ranges. It happened with every single plane, and my connection was perfectly good with pretty much zero warping at other times.
