I just did a test with real-weather-fetch at KSLC. When I set the altimeter using the QNH in the metar -- 29.76 -- the altitude is right on, as far as I can see. It's true that this pressure doesn't match the pressure shown in the Environment Conditions gui, 29.814, but that is to be expected; that pressure is now the true pressure at sea level, not the altimeter pressure.
