public static bool usesLoadStoreActions { get; }

Use this property to check if RenderBufferLoadAction.DontCare or RenderBufferStoreAction.DontCare could result in actually discarding RT contents. For example, if you render with non-fullscreen ViewPort, you do not want to discard RT contents. Note that some Unity API can use RenderBufferLoadAction.Clear to clear a RenderTexture even if the Graphics API does not support RenderBufferLoadAction.Clear directly. In this case, Unity issues the normal Clear call.
