Enum OculusSettings.StereoRenderingModeAndroid

public enum StereoRenderingModeAndroid

Name	Description	Value
MultiPass	Unity makes two passes across the scene graph, each one entirely indepedent of the other. Each pass has its own eye matrices and render target. Unity draws everything twice, which includes setting the graphics state for each pass. This is a slow and simple rendering method which doesn't require any special modification to shaders.	0
Multiview	Unity uses a single texture array with two elements. Multiview is very similar to Single Pass Instanced; however, the graphics driver converts each call into an instanced draw call so it requires less work on Unity's side. As with Single Pass Instanced, shaders need to be aware of the Multiview setting. Unity's shader macros handle the situation.	2
