I normally disable the nvidia audio because I never use it anyway. Just another thing to take processor cycles away.
Changing IRQ to a negative number is exactly what you want to see. Please let me know what the latency results are. It would be interesting to compare before and after results
Almost 2 hours of just sitting on desktop with chrome open, went afk for over an hour as well. Nvidia driver casues biggest DPC latency. Wonder what an AMD GPU would be like. Either way im not experiencing any issues with audio etc.
That looks ok. While the highest latency is the nvidia kernel mode driver, it is not actually that high. I wonder what the graph would look like with and without MSI on under gaming?
Your HD audio may benefit from the MSI treatment.
Was Chrome open with one of those pages with lot of animations and java script type applications? Chrome creating lots of hard page faults and using CPU used to be resolved by clearing the Chrome cache and still may be a thing. It seems that Chrome will allow the cache directory to get large over time. Periodically it will index the cache in the background taking up large amounts of memory and CPU resources while not reporting to the operating system with much detail.
