Interactive slower than photoreal?

snickerbob

New to iray so forgive what may be obvious.  From everything I've read I should expect interactive renders to be faster than photoreal.  With a single character, a scene and an "IRay Worlds" dome, I'm finding interactive renders to take much, much longer, and also nothing in the scene is lighted except the figure; elements of the scene are barely visible.

Am I missing something obvious?

Interactive is somewhat different from Photoreal - one of the diffrences is that emissive (light-emitting) surfaces don't produce light, so the scene may well be darker adn slower tor ender if it was mainly relying on emissive surfaces for its lighting.
