So I need some education here. I have a few different setups one of which is my surface pro 3 with ableton and BIAB installed on a Samsung external ssd. I have always just used MME or if I am in my shed using my novation keyboard I will use ASIO with a Berigner q802 USB mixer. I have never really used the USB audio connection but decided to try it toay. With the new windows 10 creator update ASIO was really having issues. I used MME with the windows USB codec/(which I did not know even existed) Ableton said my latency was about 63ms but I truly could not hear any at all. buffer was set to approx. 3700, which seemed high. Once I tried to go below that I had issues.

Set BIAB (2017, latest build) to the same and again no latency at all with both programs running. I can usually notice some latency around 30 to 35ms.

So my question is did something change in the way that windows handles audio? I was really surprised that performance was so good.
