I'm having a huge problem with the Fps droping from 60 to like 5 when crouching it is unplayable and it drops aswell when I look down but not as much as when crouching.

Does anyone know how to fix this?

And please dont tell me this is because of my Pc bacause it's not I have been running it on high settings with no problems what so ever and the crouch Fps bug just showed up like 3 days ago.

Looked through google for some answears and these forums but found nothing but stupid answears to the question....
