Audio Drivers and Performance

So thankfully the stuttering right out of the box isn't as prominent as last year, but something I have noticed is some micro stuttering everytime the ball gets brought up and the player is nearing the three point line.
I remembered this solution from last year, where turning off your audio devices completely solved the problem - and would you look at that, it also works for me in 2k17. I didn't do this in 2k16 because it was playable enough, so I guess I'm asking the question now I should've asked a year ago.
What is happening there? Is it bad optimization or is it simply a case of freeing up processing power due to the lack of audio that can be used for other things?
I really wonder how I can combine this performance with some game audio.

i have terrible audio stuttering also ;(
You disable the device to fix yours?
