The Steam forums are hot
with an issue with Call of Duty: Black Ops
. It seems that no matter what kind of system you have, the game will start glitching and become unplayable after a certain time. People are getting stuttering through the menus and general unplayability even if they can run the previous game on all high settings.
Whether it's a Steam problem or a Black Ops
problem, we don't know yet but let's hope the the issue gets found quickly and a patch comes out to resolve it. I've been looking forward to the PC version of this game and to have it unplayable would be a big disappointment.
Someone suggested to get around this issue is to start Steam in offline mode, start the game, and then go kill the Steam service. That would mean no multiplayer until this is fixed.
