How to make Call of Duty: Black Ops run faster on your PC
"如何令電腦運行COD快點"
經本人測試已經100%完全解決多人連線LAG的問題!

我只翻譯重點句子：
Switch Anti-Aliasing to either 2x or off, turn anisotropic filtering down, and switch Shadows off entirely. These are by far the biggest performance drains. If you need a little more speed, set Texture Filtering to just Bilinear.

把AA(Anti-Aliasing，反鋸齒)開到2X或者off，AF(anisotropic filtering)調低(我建議調到沒有)，還有將Shadow關掉(off)。 ..........................。如果你想要更快，將Texture Filtering切到Bilinear.

Clean Up Your System
CODBLOPS is a very system intensive game, so before even firing it up, make sure it has as many resources available as you can throw at it. Shut down any apps like BitTorrent, web browsers, instant messaging tools, Skype type tools and music apps – all of these soak up memory and/or bandwidth that CODBLOPS will want to use. If your antivirus software has a Gaming Mode, remember to switch it on before starting the game. It's also worth running the Windows Disk Defragmenter application to make sure your drive is properly organised. Finally, double-check that you're using the latest drivers for your graphics card. If you're using AMD (ATI) drivers, Steam can update them for you. Nvidia users, go here.
If you're only playing the single-player campaign, try running Steam in Offline Mode. For multiplayer, make sure CODBLOPS gets all the bandwidth by right-clicking on 'Call of Duty: Black Ops – Multiplayer' in your Library, selecting Properties , and unticking 'Enable Steam Community In-Game'.

清干凈你的系統(tǒng)
COD7：Black Ops(以下稱本作...懶得打那么多了)是很吃資源的游戲，所以要玩之前，請將一些背景程式關掉，像是BT、瀏覽器、即時通、Skype還有音樂撥放器，這些程式會占掉一些記憶體，如果你的防毒軟體有Game Mode(游戲模式)，在游戲前請將它開啟。還有記得一段時間要用磁碟機重組程式。最后，記得要檢查你的硬體驅動是否為最新，ATI(AMD，我不喜歡叫AMD)卡請用Steam上方的"檢查顯示卡驅動程式更新"，NV......(其實NV也可以點，他會導引你去NV的官網)。

如果你只要玩單人模式，試著用Steam Offline Mode跑(前提是要先更新完畢，更新完好像要先啟動一次，才可以在離線模式開啟...)。多人模式請先確認你的"在游戲中開啟Steam社群"要點掉(去勾勾就是了)，作法：找到本作多人模式--->點右鍵選內容--->就可以看到"在游戲中開啟Steam社群"--->去勾勾。

1. 裝好游戲
2. 單人&雙人都更新好
3. 下載BlackOpsConfigEditor (這是一個官方發(fā)出的解鎖設定工具)
小工具下載: http://www.gamersky.com/Soft/201011/26625.shtml

BlackOpsConfigEditor 用法:
打開工具->Load Config->Steam->SteamApps->common->call of duty black ops->
players->config_mp.cfg 之后Save Config
 
BlackOpsConfigEditor 入面有好幾個選項, 是依照你電腦情況去選擇是OR否
而我是依照英文詳解中的圖片來設定!
 
還有英文詳解提到, 這次COD是非常吃資源的游戲, 建議大家關掉一些非必要的程式才運行游戲! 例如:BitTorrent, web browsers, instant messaging tools, Skype type tools and music apps ....

還有官方有提供直接在游戲內改的指令：(官方說失敗才要這樣做...)
/cg_drawfps 1
把內建的控制臺打開(可以看FPS是多少的那個)

/stoprecord
官方說沒幫助，但是其他玩家說對口吃(?)有幫助。

/com_maxfps 100
鎖住最高FPS幀數(shù)。官方說希望使效能更加穩(wěn)定，限制是效能低落時使用。
/snaps 30
/cl_maxpackets 100
/rate 3000
這串指令和CS、TF2的cl_updaterate、cl_cmdrate很像，請照官方的建議吧。

大概就是這樣子，如果有錯或是要我修改，請多多指教。
希望這篇文章可以頂至，幫助別人。
