常聽見有人說用windows 7玩網路遊戲的時候網路延遲比較高,也就是ping比平常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,這個服務叫做: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 appible 到
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 AvSetmMaxk 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,那我們要如何解決呢?很簡單,禁用它就行了。
停用方法:開始--運行-regedit,展開[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Audiosrv]雙擊開啟右側的DependOnService項目,把MMCSS刪除(千萬別刪除到其他的),儲存。
重開機後設定才會生效,然後到服務關閉並停用Multimedia Class Scheduler,再進遊戲看看有沒有進步呢?
