It is recommended to use a modern device which is not older than 2 years and offers full OpenGL support. The device should reach at least 4800 points in the 3DMARK Sling Shot test in order to guarantee a smooth 3D performance. The 3DMARK app can be downloaded from here
if you want to run the benchmark on your device. If there are performance problems on older devices, you can turn off realistic shadows in the game settings.
