How to disable the Breathe animation?

Title says it.

Ever since Garry put up the breathe animation for players, I have been trying to find a way to disable it, yet with no luck.
Anyone got some suggestions on how to disable? As I find it unnecessary on some of my gamemodes and it reduces FPS aswell.

PAC2 found a way. But I doubt the animation reduces fps [img_thumb] [/img_thumb]
