Call of Duty: Black Ops gets performance, bug fixes on PC

By on
Despite Call of Duty: Black Ops' successful sales, it didn't exactly have the smoothest of launches. Many users complained of bugs and performance issues that made the game unenjoyable for some and unplayable for others. Treyarch has been working to solve those issues and last night the developer released a massive patch for PC users.

The list of changes is pretty extensive -- at least compared to previous Black Ops patches. This update further tweaks performance for dual-core machines, along with "additional performance optimizations." There's also a fix for random freezes on certain computer configurations, an option to pre-cache all shaders during load time, and more.

The Xbox 360 and PlayStation 3 versions of Black Ops received a similarly hefty patch earlier this week, addressing various multiplayer bugs, exploits and imbalances. PC users should get an automatic update via Steam. Have the updates solved your issues or does the game remain plagued with unaddressed bugs? The full patch notes are below:
