For all the PC players out there, we have a few tips and tweaks that should help you get the most out of your PC performance while we await a patch that Treyarch is in the process of developing and pushing out.
The following tip was submitted to us by a member of the staff over at Curse.
Here are a few tweaks that will help you a lot:



Install latest directx version (this helped the most) – you can grab that here.
Install new graphics card drivers (ATI and Nvidia)
Make sure to allow Black Ops to use multi cores: go to your steam folder, which was Local DisKSteamsteamappscommoncall of duty black opsplayers for me. This may vary for you, however. Search for “seta r_multithreaded_device 0″ and change it to “seta r_multithreaded_device 1″. Do this for singleplayer and multiplayer.


We hope that this helps increase your PC performance while we wait for Treyarch to get that sorted out for us. We know they are working hard on that for us, but we’d like to give you the best game you can have while we wait.
Good luck and feel free to let us know in the comments or over at the forum how this worked for you, and don’t hesitate to throw any more tips and tweaks out there for the PC community.

1.安装最新的Directx（效果最大）
2.安装最新的显卡驱动
3.进入steam文件夹，找到player文件夹下的config.cfg，打开，查找seta r_multithreaded_device 0 并把后面的0改成1 （允许游戏以多核心处理）
