Just a heads up for people considering upgrading to Windows 10 2004 when it's released…
Most people would be using Windows 10 1909, but with the upcoming 2004, something is not working right with Breakaway Pipeline 4.15. Basically nothing but stuttering.
So I tested with Virtual Audio Cable 4.62 and it was the same, however, setting "Ms per int" to 1 fixed it. For some reason setting this to 1 on Breakaway Pipeline 4.15 has no effect. I'll keep playing around and provide any updates, but someone more knowledgeable about how virtual cables work might want to take a look at this.
EDIT: Ms per int =1 is not a fix. Some programs will trigger the stuttering again.
EDIT #2: Running VAC 4.6.2 with Ms per int set to 1 and only 1 cable seems to be the most stable solution for now. Anything else is hit and miss.
