Call of Duty Black Ops' PC players just got the first patch update to the already mega-selling first person shooter from developer Treyarch and publisher Activision. The patch, delivered via Steam's auto-updater, has just a couple of mutiplayer oriented bug fixes but hopefully they will deal with some of the performance and lag issues that have plagued the PC port since it was released on Tuesday.

Specifically, the first PC patch has some "performance improvement for dual and quad core systems". Many of the game's issues have been linked to its CPU performance. The other note in the patch is for a "Friends fix for join in progress and Friends tab in server browser." This is almost certainly to be just the first of many bug patches for the game.
