Massive fps tank when I pose anything or change model

So whenever I use anything with my pysichs gun at all no matter if its a ragdoll or random prop I get a flipping MASSIVE fps tank. I dont know what I did to cause this because this never happened to me before! I used to be able to pose things just fine. Everything else in the game is perfect but basically all i do is pose stuff so this is a major issue for me! The fps tanks also happens if I open the C menu and try to change anything in there. I havent tried re-installing or anything yet and I havent seen anyone with this same problem. If anyone has a solution I would love to hear it, Thanks!
