    Well last week heard what I thought was a dpc latency related audio stutter on in the MW2(1:21sec in) video everyone said I was probibly wrong and thats the way the game sounds. I got my M11x in on the 3rd and not 10min ago I am working on my physics homework on webassign and listening to music and I hear a stutter. :mad: I immediatly dloaded dpc latency checker and this thing is riding at a steady 3k with the occational spike. I dont wanna even try to solve this problem as I just got the problem fixed on my M17x a few weeks back and it was a headache as many of you know im sure. Im just relaying this info to the rest of you guys out there. This thing runs pretty good except for that. Super fustrating. grrrr

    Audio interrupts caused by DPC latency (with the NV GPU driver) will display as a 65k+ spike on that freeware checker. I don't believe it is the cause.

    I am trying to replicate it to figure it out. I happens mostly when I submit my answers or tab through windows.

    When I turn off the Nvidia card it goes away completly. This is when I use fn+f6 also spikes to 19k. Cyberlink youcam when opened gave 24k spike.

    Quiet, why dont you take a look here and if you are interested in getting to the bottom of this, try out the process outlined in post# 1. I'm Stamatisx will have no problems with helping you to understand/analyze the results.
