10-20 fps in BO2 online. + BO2 zombies camera issue

[Tannsannd]

I just got plutonium and T6 set up and I am having a problem on every server i join where I only have 10-20 fps which is completely unplayable. Any help there?

Also when i try to play zombies my camera moves in a super weird way that I dont know how to describe. It basically just moves super fast and spins my character around. Help on either of these would be really appreciated, thanks.
