Yes, there is.
Here is the list of settings that must be disabled in order to deactivate 3D Radar overlay completely:
- 3D Radar tab -> Show -> Nothing.
- 3D Radar tab -> Show FATEs -> List / World.
- 3D Radar tab -> Show Gathering -> Out of reach.
- Navigation tab -> Show on radar.
- Gold Saucer tab -> Racing -> Show -> Rails / Mid-rail / Progress / Waypoints.
- Combat tab -> 3D Radar -> Show arena.
- Combat tab -> Assist -> Pause -> Show pause status.
You can verify that 3D Radar is deactivated by looking at the top left corner of the game.
- If you see a transparent box, it means 3D Radar application is rendering the overlay window.
- If the top left corner is empty, it means 3D Radar application is deactivated.
