Zooming
From Exilent
Zooming can be done with scrolling the mouse wheel.
Zooming has the following settings (Client - Settings - General - Zooming):
Use client zoom: wether to use this feature. Changing it requires a client restart.
Increase rendering distance: with this turned on a bigger piece of the game will be rendered. Turning it off can improve the frame rate.
Zoom speed: how much one wheel tick changes the zoom value.
The zoom value is displayed in the menu bar.
