After installing Fallout 4 on a brand new PC, I noticed a weird looking “radar” overlay on screen with reference to sound settings that I couldn’t get rid of. Turns out that this is part of the “Sonic Radar” tool that gets installed as part of the Asus driver package. The problem for me was that I couldn’t find an app to turn it off – nothing on the Start Menu, Control Panel or anywhere else.
Thanks to the ASUS Forums, I found you can download the Sonic Radar 3 utility from the Microsoft store here.
Once installed, run the app, turn everything off and the overlay disappears.
