Hello all,
I'll try to make a somewhat long story short. A couple of days ago I found my computer running unusually slowly when gaming. My computer isn't a powerhouse, but it's run just fine with certain games like GTA5 and Civ 5 if the graphics options have been tweaked appropriately.
My sound started dropping out, sounding static-like. Tried checking the headphone jack and speakers, which turned out to be fine on their own. As I was playing, the framerate would drop out with the noise seemingly trying to catch up as well. After trying a number of regular things such as turning off programs that suck up CPU usage and memory, it still didn't help. Opened up my laptop and cleaned it out with an aircan, thinking it might be due to dust. Still, no dice.
I read somewhere that it could be due to high dpc latency, so I downloaded LatencyMon and a dpc latency checker. After letting them run for a number of times along with Windows xperf, it seems as though ndis.sys was the issue. I downloaded SlimDrivers to check on driver updates and it found that my network adapter (Qualcomm Atheros ar9485wb-eg) needed a new driver. Downloaded that, installed it, and still dpc latency was high. Tried disabling it via Device Manager and playing a game, still no dice. Found another possible driver causing the issue, hdaudbus.sys, causing high latency. Can't find a fix for this or ndis.sys through other posts and tutorials. Even tried going from Windows 10 to Windows 8.1 to see if the drivers would work better on the OS type, but it made no difference.
Here's my specs:
I'm not one to usually post on forums about computer issues, as I can usually solve them on my own, but this latency issue has stumped me.
