this type of lag happens even without the fighter, Usually see it with big ships (likely why people think it's the fighter). But most cutters/vettes out in the open are laggy this way after a bit of time in combat.
Nope, not like the guy I was hinting about in my post.
And no, it's not normal to have a ship of any size jumping around a 300-500m each time you try to line up a shot.
Anyways, let's not derail the thread.
