With my system it said I should disable "CPU throttling".
Salem Beats, thanks for the post.
In regards to the screenshot you have posted, what type of system do you have? Can you let me know please.
I have my system specs listed on my
"Salem Beats Uses..." page.
However, the screenshot I posted isn't of my system.
Instead, it's just a stock photo I grabbed off the web.
My system runs a lot lower steady DPC latency than the screenshot:
About 20-80 microseconds with everything hooked up,
with a short 400 microsecond spike from the nVidia drivers once every 5 minutes or so.
I don't have a USB audio interface
(I use a native internal PCIe card, as you can tell on my list), and
not having one generally helps with DPC latency.
This is because with most systems, all USB devices end up being processed by the same hub, and each of the devices gets in one another's way.
When you have a USB audio card, the requests it submits to your CPU to fill its audio buffer can be interrupted by the mouse's requests to update cursor position, a USB keyboard's requests to enter key combinations, etc.
Speaking of DPC issues - I've had an issue in the past where simply replacing an
(apparently innocent and working) USB cable fixed a DPC issue I was having with my USB drivers.
Although it appeared to work just fine on the surface, presumably it was
partially damaged, and therefore needed to re-transmit some data packets, causing a lag on the system as the CPU needed to wait for these packets to be received before the system would allow it to work on anything else.
Hence, high-quality USB cables with no kinks are a surprising
"must-have" for high performance in a computer that uses USB devices.
I don't buy those $2-for-4 USB cable packs from Amazon/eBay like I used to.
