Rendering
Shadows
Enable/disable shadows in the scene. Shadows make the scene more realistic but they can hurt the performance on low-end devices.
Ambient occlusion
Enable/disable ambient occlusion from the scene. Ambient occlusion is a rendering technique which modulates the amount of ambient light received by areas of the scene, depending on how exposed they are. This setting can significantly improve the realism of the scene but also hurt performance on low-end devices.
