Win7 online game PING high cause and solution

            I often hear people say that when using Windows 7 to play online games, the network delay is relatively high, that is, the ping is higher than the usual xp, and the reason has been found, it is very distressing. Today we finally found the reason. It turns out that a service of Win7 is blaming. This service is called: Multimedia Class Scheduler. The official explanation of this service is: The Multimedia Class Scheduler service (MMCSS) enables multimedia applications to ensure that their time-sensitive processing The 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 determines 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 is this service let My PING is so high, the problem is to find , Then how do we solve it? Very simple, just disable it. Disable method: Start--Run-regedit, expand [HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Audiosrv] Double-click to open the DependOnService project on the right, delete the MMCSS (do not delete it), save it. The settings will not take effect until you restart the computer, then close and disable the Multimedia Class Scheduler in the service, and then enter the game to see if there is any improvement?
