cc. when you stick stir your plane rolls and displaces itself over your screen.
Most times what you see is a 190 that rolls and has its topside banked to the left then the plane suddenly warps a few yds to the right while retaining its same position (that is , banked to the right). The pilot is NOT banking and pulling nose down to get that effect, when they do that the plane's nose and tail dips accordingly, in the stick stirring what happens is what urchin describes above.
Another kind of warp roll is the kind that a P-38 can do when its missing a wingtip. You have to pull the stick Up and down while applying rudder and flaps to keep the thing from losing control or augering. When in this situation, many enemy cons have tried to attack me. I cant even turn at ALL, the best I can do is wobble up and down and hope to throw their aim off. Since I have to apply the rudder and pull stick up and down and to whatever side the missing wing is, the plane changes vectors very erratically. The red guy's FE cant update so quick and he generally sees me flying straight and wobbing up and down a bit then ZIP my plane suddenly is a few feet to one side and 100 ft or so above or below the position I was before the ZIP.
Its not lag on my end or his, it seems the FE dont update so many inputs. This is my guess.
190's do it a lot (their great roll rate is bound to be the culprit
), but any plane can do it. Some players have even become experts at it.
