I've been using ASIO from the start. What little I know about WASAPI is that it's Windows answer to ASIO. Very similar in how it acts and if I understand correctly, it allows sharing mode so that multiple audio devices can use it at the same time. It is supposed to be a low latency driver. It allows bypassing of the audio mixer and the default settings according to what I read. It is recommended as an audio driver when MME, and ASIO are problematic in one way or the other. If your ASIO driver provides excellent service, there is no advantage to using WASAPI.

It is simply one other option to use for running an audio product. It is proprietary so the device or software has to be designed to be compatible with WASAPI in order to function properly using it.

AS far as PG adding it to the compatibility list, I think that would be a good idea since some people may actually find that WASAPI is the fix they need to run a low latency system with some of the off brand interfaces on the market.
