NDIS is still spiking ... what else could be causing it??
(With the LAN disabled, and with both the Intel 5100 & the AR9285)

[SOLVED] Could somebody tell me what is causing my high DPC latency in Windows 8.1?

Do you still have audio glitches?

Here is a list of all the drivers that are active: https://drive.google.com/file/d/0B3-yyU44xFecbjR0aUxiNU9vZnM/edit?usp=sharing

I'm really sorry to hear that you are still having issues, but, unfortunately, I no longer see a point of keep troubleshooting this as a DPC issue. As per the screenshot below (made from the latest XPERF report you attached), your CPU usage is still very high and the larger part of that load comes from user-mode (not DPC/ISR) - Flash, to be more specific.
Until these issues are resolved, it is not worth expecting good performance of the system and looking problems in other places (especially, going and disabling random drivers (webcam, touchpad etc.) like you just did).
By the way, video card driver on your computer is 8.14.10.2697, while the most recent one is 8.15.10.2697. There are some chances the latest drivers improves compatibility with Flash, enabling hardware decoding support. Please try installing these drivers.
Good luck.

GOOD NEWS!!!
I just installed 7.15.10.1666 and audio played fine with minimal CPU usage 480P IN DRAGON (I red up on the error code that chromium gives and it relates to the 8 series driver - https://code.google.com/p/chromium/issues/detail?id=180695) I would of tried 8.15.10.2697 but I read the tread and thought I'd try the 7 series "original" driver.
It also does the non-smooth "blip" when it goes into full screen (hardware decoding glitch when it changes sizes?)

I did a noobish look at the DPC and everything was "A-OK" (CPU usage under 40%) apart from ndis.sys (It seems ACPI was down to the GPU driver??? I'm probably confusing myself now LOL)
Seems like I'll be messing with AR9285 / Intel 5100 drivers now?

Your last trace looks just fine:
CPU load is ~55% per CPU, DPC duration is ~2% per CPU (this is really low and the issues usually starts when they are at 10% at least), IRPs duration is ~500m % per CPU, which is great.
To sum up, you shouldn't had any audio issues during the last trace and I'm not sure what else you are expecting to find here.

It is great.
To sum up, I:
Removed the Bluetooth adapter
Changed the wireless adapter to a Intel WiFi link 5100
Downgraded the graphics driver to 7.15.10.1666
Updated the audio drivers with the latest driver from Realtek
Am very pleased :)

I'm really happy to hear that.
Can we consider this case solved?
