I've been troubleshooting latency issues with my PC for a good couple of weeks since I was getting audio crackles and issues with video and audio streaming. So far I've managed to eliminate the worst of it by getting a pci network card instead of using the on board one, but I'm still ending up with these intermittent spikes on DPC latency Checker.
Unfortunately the message board isn't letting me post images at the moment, but visually it's a spike of 2556 us about every minute and five seconds. Sometimes lasting up to three seconds. Is this something worth looking into or should I just leave it be?
