Heavy lag after patch

Now my PC never really played it as smooth as i would like but with all of the graphic setting turned down in the game and on catalyst it ran pretty good. But once i started playing after the patch It's been lagging like crazy! Sometimes while i'm running it will completely skip a frame. Usually when you switch to passive and active mode your character stops to take out/put away weapon and now when i take a weapon out my character shows the motion but still moves. It's forced me to stop playing it's so bad. Anyone else experiencing these problems or knows how to fix them?.... Also i just remembered when i choose my character at the beginning and your characters show up, It lags REALLY bad there too. And it NEVER used to lag at the menu there. Why would it? It's not doing anything hard it's just showing my characters.

Never mind. I got it to work.
