Iray Preview not showing scene as it renders

RLSprouse

I have a simple scene with a few primitives inside of a big box, and I am playing with emissive surfaces to provide light, experimenting with different settings. When I render the scene with Iray, the results I get are as expected, but the Iray preview looks very different. Why is this, are there settings that affect the preview differently from the actual render?

Draw Settings controls the preview - when the viewport is in Iray mode. Interactive mode, as I recall, does not support emissive lights (in the Drawing group of properties).
