I'm having an issue with the frame rate on zombies for black ops. Everything goes fine until the mid twenty level mark when the frame rate begins to take a hit to the point where its barely playable. It only every happens when there are four of us in a party.
We've tried everything, upgrading our connections (3 x 30mb and 1 x 20mb all Virgin Media), changing our routers and even different machines but the same thing keeps happening.
I've done some searching on the web but there's barley a mention of this sort of problem baring a few people who are having similar problems.
Anyone had the same or know what the issue is?
Any help appreciated.
