In fact, radiance is simulation software with high accuracy. But 
you can fine-tune all parameters, so can use it as a simple 
renderer. If you are concerned about performance, take a look 
at the ambient parameters, they have the biggest impact on 
rendering time. Excluding most materials from ambient calculation 
and setting good av-values might help. 
 
Of course, radiance is not an easy renderer, but you get lots 
of very powerful tools for cad-import, image processing, previews 
and scripting tools. 
 
Good luck, cu Lars.
