It's been a few days since I tried the solution and everything is in the green (literaly! )
I even tried running 3DMARK06 to see if it made any dent in my graphic performance and it didn't.

My latency stays in the green until I open a bittorrent client then all hell breaks loose. I don't run a graphics card as I only a built in card. My problem is DEFINITELY related to my ethernet adapter. As soon as I disable it, all latency disappears.
I am convinced it is Windows 7 and the way it is interacting with various drivers is the issue.
It is the only common factor it seems in all these posts, and didn't seem to be a wide spread problem until recently, at least looking at various post dates on different forums since I started researching it.
Powermizer switch does not work on a Desktop PC. It comes up with an error that no powermizer is found.
My PC is relatively new, but I don't remember if I had the problem from day one. I'm thinking that perhaps it appeared after some windows update. I will go over all the updates and check if anything has to do with NDIS.SYS.
Thanks for that detailed instructions. Unfortunately, none of these keys exist in my registry. (I did search for keys, values and data, some classes where found but nothing you mentioned.
Yes, the values I posted where good values with only a few spikes. DPC Latency is always higher then 16 milliseconds(!) when using the network.
Thank you very much for that, this is very kind. If only more people would come back with solutions to the forums....
I never checked for DPC latency at the beginning (when I got that computer I did not even know that this thing exists.. those were nice times...)
It is clear for me now that DPC latency can have more than one cause and it is therefore not possible to find a one-for-all solution. I'm sure your solution will help some people with laptops and I hope someone will find a solution for me too.
Did you check to see if you have this service in the services list? (management console)
The Base Filtering Engine is related to the Windows firewall. If you don't have that service, try to restart your firewall service, and see if that resets the DPC latency.
yea it gives an error and asks if I'm sure and it might not work on older drivers or something I just clicked yes and everything is ok. but like I said, maybe there are different problems here. The only main thing connecting everything here is WIN7 .
by the way - I disabled all updates to windows as soon as I installed windows, and the spikes were there nonetheless. for me at least, I don't think it was an update issue.
Not a windows update issue. I think windows without any other software installed may work fine. But a soon as you install programs that actually USE the machine (like a fileshare program) you will get problems.
I don't have DPC lag when I don't surf. But that can't be the solution on a modern machine.. if I don't surf and only want to listen, I can use the ol' ghetto blaster.
