That's so odd that vibration on controllers is causing lag for you. I believe there's an option in the oculus app to accomplish this, but only if you have dev mode enabled. If you do, you should be able to go to tracking and controller, scroll all the way down and there should be an option to adjust vibration level.
Take your destiny into your own hands. Sand cannot keep a shape by itself, but add water and it becomes malleable. Fate can be such, if you add the right element.
