No lux is definately longer. The reason I like it better is due to the fact that the DS 3D light engine has not evolved much since DS3A in my opinion. UE renders still come out more or less the same. I have gotten many nice renders but like you. I am coming up on a year of lux rendering and managed to get it where I can use it for my needs... I look forward when Paolo updates Reality so I can start using 2.1
