DIALux evo is much faster and better
DIALux evo was launched in 2012 and is replacing the old DIALux 4.12
In the future there will not be update of DIALux 4.12 or DIALux 4.13
Is generation “evo” better than generation 4?
Actually DIALux evo is much more faster with better rendering, better handling of complex model and has different concept of construction, applying material, light and making the calculation.
Is DIALux evo ready to replace the current generation 4?
Yes the only pending feature is emergency lighting and sport lighting which is expected to be available by end of 2016, after that DIAL might not give any further support for the old DIALux 4
