解決Win7下網絡遊戲PING高原因及辦法

經常聽見有人說用windows 7玩網絡遊戲的時候網絡延時比較高,也就是ping比平時xp的時候高一點,一直找不到原因,很苦惱。今天我們終於找到理由了,原來是Win7的一個服務在作怪,這個服務叫:Multimedia Class Scheduler,

  這個服務的官方解釋是:

  The Multimedia Class Scheduler service (MMCSS) enables multimedia applications to ensure that their time-sensitive processing receives prioritized access to CPU resources. This service enables multimedia applications to utilize as much of the CPU as possible without denying CPU resources to lower-priority applications.

  MMCSS uses information stored in the registry to identify supported tasks and determine the relative priority of threads performing these tasks. Each thread that is performing work related to a particular task calls the AvSetMmMaxThreadCharacteristics or AvSetMmThreadCharacteristics function to inform MMCSS that it is working on that task.

  For an example of a program that uses MMCSS, see Exclusive-Mode Streams

  就是這個服務讓我的PING如此高,問題是找到了,那麼我們如何解決呢?很簡單,禁用它就行了。

  禁用方法:開始--運行-regedit,展開[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Audiosrv]雙擊打開右側的DependOnService項目,把MMCSS刪除(千萬別刪到其他的),保存。

  重啟電腦後設置才會生效,然後到服務裡關閉並禁用Multimedia Class Scheduler,再進遊戲看看有沒有提高呢?
