I finally fixed my Laggggg.....

Finally after months of tweaks and research I stumbled into getting my lag fixed. The details below might help some of you.

For the last couple of months I have been experiencing what most people call Lag. The weird thing is my ping was stable and the FPS mostly above 30 fps. I still felt like I have to drag myself through the map. I couldn't aim well. It was almost impossible to play full rooms and may times my hit wont register.

Now the solution part:
Windows 7 and vista has this system of allocating processing power for video and audio using some weird logic. What was happening to me was mostly due to my audio. The more people in the room more the sources of audio. And then my PC starts allocating more processing power to process audio that video. This is done using a service called MMCS.

After some extensive research I stumbled across a tool called DPS Latency checker (http://maxedtech.com/the-case-of-dpc-latency/). As mentioned in this site I started disabling and enabling each of my drivers. And finally figured out my Corsair Vengeance surround sound headset was mostly causing the processing to delay video processing. I switched it from dobly (5.1) to stereo and the problem disappeared

So what most of us have been calling as lag (when ping and frame rate are stable but game draggs) was actually windows dropping video and audio frame rate as part of balancing whether audio or video should use the processor.

Hope this helps some of you.
