Resolution and sampling level of the interactive engine can be set exactly as in the final production one, and also the image can be saved to disk. Actually you can even launch maxwell.exe in preview mode for generating quick animations, let's say 5 seconds per frame. We will need to change the time control of all the GUIs in studio and plugins to accept seconds :)
It's not totally safe, actually today I've showing some demos of interiors and results were not bad at all. Of course in general they don't clean as fast as exteriors but they give you very fast results in seconds, so the setup time is dramatically reduced which is the main point of the interactive engine.
