When this is enabled (type "crosshair 1"), the engine will draw a plus sign with the Quake font in the centre of the screen.
Some engines support different crosshairs, using internally stored graphics or drawn from external TGA images, in which case you will be able to change the look of the crosshair by setting it to 2, or 3, etc. There is no standard how those crosshairs will look like. Using the same config in different engines can results in a differently looking crosshair.
