i would recommend to try it out. it is highly hardware dependent whether you will have hardware acceleration on both heads for your gfx-card or not.
to discourage people from using it, is similar to discourage people from using full-duplex audio, just because my crappy soundcard/driver does only provide half-duplex (these days seem to be gone thankfully; but then: i would not recommend to use a microphone, since the one in my laptop sounds terrible :-))
