How do I change Graphic Quality?
Graphic Fidelity strongly depends on the GPU of your device. The default graphic quality is at the maximum level of details settings which passed our Quality Assurance tests. However we provided a feature for some devices to lower the settings which may improve the overall gameplay speed.
All you need to do is open the settings (cog icon in the bottom of the screen) then go to Video options and chose the quality level you wish to use in the game.
