I can say that i've never had problems with the RME drivers,
especially ASIO with various applications.
If there are problems i suspect them to be related to some old
portaudio code used in Pure Data.
Up-to-date portaudio versions work flawlessly with RME drivers.
Concerning MMIO i can hardly imagine how people can reach low
latencies with it, given the architecture of this interface.
