+
+	@discussion
+		By default, whenever possible, video decode will be performed on the GPU associated with the display on which the presenting CALayer is located.  Decode will be transitioned to a new GPU if appropriate when the CALayer moves to a new display.  This property overrides this default behavior, forcing decode to prefer an affinity to the GPU specified regardless of which GPU is being used to display the associated CALayer.
+
+		The GPU registryID can be obtained from the GPU MTLDevice using [MTLDevice registryID] or can be obtained from OpenGL or OpenCL.
