Plutonium

So i playd a bunch of iw5x, and since i had a pause for a while, i got into the game again. The launcher updated few things apperently, and after that update, my FPS in the Class editor, and everytime i choose a Class in match, is like below 2. I dont know what that is, and i just want to know, if u have a fix for me.
