Disable the overlays
If you do not want to see the overlays in-game, this guide is for you. After this, you will still be able to use Dispatcher, Achievements, Modhub and all other features, or even re-activate the overlays if you wish.
You must disable “Open main window at startup” and “Open game info overlay at startup”
Then, disable “Enable traffic reports notifications”, “Enable audio on traffic reports and notifications” and “Enable traffic report when entering an area”
There you go, you disabled all visual overlays in-game!
