What I find disappointing about these rendering images is that they usually don't account for important aspects of a game engine. They might have a lot of rendering options, but they usually lack important scene optimization, like a good portal or BSP system. You can kind of tell when their demos are just a single room, or a beautiful rendering of a single object.
Torque is the only engine I can think of that shows off an entire scene, but that engine is also painfully slow and outdated. A good rule of thumb is that a product's demo is indicative of the best you can do with it. The author would have pushed the system harder if there wasn't some limitation that prevented it.
