Audio quality is poor and there is significant DPC latency from dxgkrnl.sys.
I booted up Arma 3 and Latencymon, and beside the obviously terrible frame rate and graphics, the sound was great. LatencyMon confirmed the latency was much lower without the driver installed.
This leads me to believe it's an issue with the intel drivers? I will paste a log below of LatencyMon and Arma running WITHOUT the GPU drivers:

Your system appears to be suitable for handling real-time audio and other tasks without dropouts.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Average measured interrupt to process latency (µs): 6,726224

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

03-09-2023, 12:46 PM #11Windows support suggested I DDU my Gpu drivers again and reinstall without the support assistant. While I did that I thought I'd check what happens if I try and recreate the problem before reinstalling the Arc drivers.
I booted up Arma 3 and Latencymon, and beside the obviously terrible frame rate and graphics, the sound was great. LatencyMon confirmed the latency was much lower without the driver installed.
This leads me to believe it's an issue with the intel drivers? I will paste a log below of LatencyMon and Arma running WITHOUT the GPU drivers:

I allowed Windows to install all updates except the arc drivers and set up the motherboard drivers. I also installed Steam, Arma 3 and LatencyMon without any issues so far. DPC or audio problems haven’t appeared yet. Then I tried installing the Arc driver, but it immediately shows high DPC latency again.
I just completed testing on Windows 10 again. The same problem occurs there too.
