Plutonium

Drop in fps and sometimes the screen sticks for seconds when I play Zombies Online, when I play local (LAN Offline) this does not happen.
The problem started when the Plutonium was upgraded.
I already installed the operating system from 0, I downloaded the BO2 again and the result is the same
It is not my internet, I already tried with another network and the same thing happens
The network adapter is also not the problem
It all happened when the Plutonium was updated with the latest update.
Fix!
