The PC version of Call Of Duty: Black Ops has been patched to correct issues with its single player and multiplayer modes.
According to Techtree, the patch includes fixes to reported frame rate issues in the single player, which were reportedly caused by a lack of CPU optimisation and resulted in players having to run the game on a lower than necessary resolution setting.
The release also includes a second update to the mulitplayer browser that allows for quicker list population, improvements to the matchmaking system for the Zombie mini-game as well as repairing problems with the Steam interface.
Glitches in the game have been reported across all gaming platforms, with PS3 users being amongst the worst affected.
Call of Duty: Black Ops is one of the most successful gaming releases of all time having sold 5.7 million copies worldwide on the day of its launch.
