(hitbox fixer).
All of that crap - dramatically improve "so called" lag feeling in game.
In other words: shooting / action / motion in the game much smoother, predictable, and easier.
And in result people think that "server does not lag".
No, not really. This is pure path / algorithm side.
Try it, you will notice dramatic difference to default setups.
