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

From the release notes for 2018:
Windows Audio (WASAPI) driver format support. This allows for low latency audio recording/playback without requiring ASIO. Note: this supports 1 stereo input plus 1 stereo output at a time.

For multiple inputs/outputs, you should continue to use either MME or ASIO.
