Getting stutters when playing Multiplayer/Singleplayer

Hey, I bought BO2 today and when I entered the multiplayer mode, everything seemed fine: there was not stuttering or lag on the menu screens. But as soon as i joined the game, I started getting stutters every second! No one else on my friends list seems to be getting this problem and I've updated all my drivers and verified my game cache. I was wondering if anyone on MPGH had any idea what the problem is and how to fix it!

Thanks alot!

You running an Nvidia card? Beta drivers are available that greatly increase BO2 performance.

Same here, i'm using an ATI card.
