Quote -  You can do a lot with a bit of fakery, eg this renders in about 20 sec... yes it is firefly and no, there are no cutaway walls. The only source of light is that door on the right.

 

Low quality settings and low resolutions render very fast. No disputing that.

This is a very small image. There are a lot of artifacts (blotchiness) in the corners and on top of the couch/chair thingie. At higher resolutions, those corners would look kinda moldy. Render time increases dramatically when you want to reduce/eliminate those artifacts.

Of course, if you don't have white walls, it's not nearly as noticeable. :) And real white rooms are rarely perfectly clean.
