官网上找到了顿卡的解决办法！！！！！

echopp

To fix the lagg on COD Black Ops, do the following. （有光盘人士，请参照以下解决）

1. Go to your computer, and find the files of the COD Black Ops disc.  我的电脑，找到游戏光盘
2. There is a folder in the disc called Resources. In that folder is a redist folder. 里面会有个文件夹叫“Resources”，这个文件夹里面有个redist文件夹
3. run the vcredist_x86.exe file. 运行vcredist_x86.exe
4. Then go into the DirectX folder and run the DXSETUP.exe  然后去DirectX 文件夹运行DXSETUP.exe
5. Restart Computer.重启电脑

And then you should have the lag fixed, it worked for me and all my friends. (Might experience small lagspikes every 10-15 mins)

NO need to do the above, just go at http://www.microsoft.com/downloads/e...displaylang=en

download Directx update webclient, run it and reboot, that should fix lots of problems...




都是在官网上看到老外在试这两种办法，似乎大部分人都凑效了，有些人还是会卡~~~希望能给大家个参考~！
