The associated gamebar extension must be used in order to use Crosshair Magic with games running in fullscreen mode.
From the Crosshair Magic application (purchased via Steam), select a crosshair that you would like to use. This preset will be used by the Gamebar app.
Turn on fullscreen mode in the Crosshair Magic Steam app, or toggle off the crosshair.
First we need to install the Crosshair Magic extension from the Microsoft store. Click the link below to go to the store page.
To open the extension, press windows key + g. The Gamebar will now be open. From here, click the "widgets" button near the top of the screen and choose the Crosshair Magic app from the list that drops down.
In order to have the crosshair showing when the Gamebar overlay is closed, you need to pin it to the screen by clicking the pin icon at the top right.
