IMMERSE GAMING | Mass Effect 3 SOUND SETTINGS
If you would like to use the Sonar Map overlay when playing any game, you'll need to configure your screen setup to Windowed fullscreen/borderless. Sonar Map is an optional UI overlay found in the Accessibility settings of your Immerse Gaming software.
Please be aware that some games have started to disallow all 3rd-party UI overlays during online play.
Mass Effect 3 automatically outputs the audio in multi channel (7.1) when Immerse Gaming is running. Looks like you're ready to play!
