《使命召唤7》解决多人连线LAG的官方方法

How to make Call of Duty: Black Ops run faster on your PC
"如何令电脑运行COD快点"
经本人测试已经100%完全解决多人连线LAG的问题!

我只翻译重点句子：
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，反锯齿)开到2X或者off，AF(anisotropic filtering)调低(我建议调到没有)，还有将Shadow关掉(off)。 ..........................。如果你想要更快，将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'.

清干净你的系统
COD7：Black Ops(以下称本作...懒得打那么多了)是很吃资源的游戏，所以要玩之前，请将一些背景程式关掉，像是BT、浏览器、即时通、Skype还有音乐拨放器，这些程式会占掉一些记忆体，如果你的防毒软体有Game Mode(游戏模式)，在游戏前请将它开启。还有记得一段时间要用磁碟机重组程式。最后，记得要检查你的硬体驱动是否为最新，ATI(AMD，我不喜欢叫AMD)卡请用Steam上方的"检查显示卡驱动程式更新"，NV......(其实NV也可以点，他会导引你去NV的官网)。

如果你只要玩单人模式，试着用Steam Offline Mode跑(前提是要先更新完毕，更新完好像要先启动一次，才可以在离线模式开启...)。多人模式请先确认你的"在游戏中开启Steam社群"要点掉(去勾勾就是了)，作法：找到本作多人模式--->点右键选内容--->就可以看到"在游戏中开启Steam社群"--->去勾勾。

1. 装好游戏
2. 单人&双人都更新好
3. 下载BlackOpsConfigEditor (这是一个官方发出的解锁设定工具)
小工具下载: http://www.gamersky.com/Soft/201011/26625.shtml

BlackOpsConfigEditor 用法:
打开工具->Load Config->Steam->SteamApps->common->call of duty black ops->
players->config_mp.cfg 之后Save Config
 
BlackOpsConfigEditor 入面有好几个选项, 是依照你电脑情况去选择是OR否
而我是依照英文详解中的图片来设定!
 
还有英文详解提到, 这次COD是非常吃资源的游戏, 建议大家关掉一些非必要的程式才运行游戏! 例如:BitTorrent, web browsers, instant messaging tools, Skype type tools and music apps ....

还有官方有提供直接在游戏内改的指令：(官方说失败才要这样做...)
/cg_drawfps 1
把内建的控制台打开(可以看FPS是多少的那个)

/stoprecord
官方说没帮助，但是其他玩家说对口吃(?)有帮助。

/com_maxfps 100
锁住最高FPS帧数。官方说希望使效能更加稳定，限制是效能低落时使用。
/snaps 30
/cl_maxpackets 100
/rate 3000
这串指令和CS、TF2的cl_updaterate、cl_cmdrate很像，请照官方的建议吧。

大概就是这样子，如果有错或是要我修改，请多多指教。
希望这篇文章可以顶至，帮助别人。
