Hello to everyone having this infinitely annoying problem in Windows 7 / 8 .
All of you who had tried reinstalling the drivers and disable Audio Enhancements please look onto these two simple tools (http://www.resplendence.com/latencymon , http://www.thesycon.de/deu/latency_check.shtml ) that analyze the DPC Latency of the system.
Firstly open one of those tools and hit RUN (for the first one). The LatencyMon will give you hints about what may be causing problem,anyways you'll have to manually disable multiple drivers from ControlPanel->Hardware&Sound->Devices&Printers->DeviceManager and watch while disabling each driver which is the one that causes latency problems ( the bar should be yellow or green) . After you got the root of the problem try reinstalling the driver ( search alternatives or so for it ) and see if it works.
In Windows 8, the DPC Latency is bigger than in Windows 7 ( in W8 Iget a yellow bar in DPCLatency at best) and i hope this will be resolved in later updates so be careful with your devices/drivers.
The problem I was having was related to my Wireless device in Windows 8 that I couldn't solve yet ( I simply switched to my cable connection until i'll have more time to analyze the problem) .
Another solution I found for the Windows 8 on the internet ( a Microsoft official posted it ) was this line that you must type inside a cmd window and run it as Administrator:
bcdedit /set disabledynamictick yesThat command was supposed to reduce the DPC Latency in Windows 8 and stop freezes but it didn't help my pc to get rid of the problem, in fact I sensed no effect but it may work to you.
Lastly I thought that I could buy an wireless usb adapter that should solve half of my wireless portability problem. I'll post any news if the adapter will do the trick.
Hope it will help you, if not ..Where is your Guru now?
