DIALux 3.14 stems from an era where mathematical accuracy eclipsed complex 3D rendering animations. Instead of requiring dedicated modern GPUs, its primary mechanism targets fast arithmetic processing of the lumen method and point-by-point calculations.
If you must run Dialux 3.14 for archival purposes, ensure you operate it in an isolated sandbox or a virtual machine running a compatible legacy operating system to protect your primary workflow. To help you find the right tools, please let me know:
DIAL GmbH introduced Dialux to give lighting engineers, architects, and manufacturers a standardized platform to simulate light behavior in three-dimensional spaces. Dialux 3.14
Long-time users are deeply familiar with its quirks and reliability.
Dialux 3.14 has one of the best false-color rendering engines for print. Go to Results > Calculate (F5). Then, Results > Isolines . You can print these isolines directly to PDF. The clarity of black-and-white isolines from 3.14 is often cited as superior to the color gradients of evo for technical documentation. DIALux 3

It sounds like you might be referring to (often typed as 3.14 due to the proximity of the keys or confusion with the Pi number). The "DIALux 3" series was a very old software generation; version 4.14 is widely considered one of the most stable and classic releases before the modern "DIALux evo" era.

Select luminaires from imported manufacturer catalogues and place them in the layout.
Before the modern, high-powered DIALux evo 13 took over, t14 . For many veteran engineers, this wasn't just software; it was the reliable workhorse that designed the first energy-efficient offices and complex city streetscapes of the new millennium. Version history - Knowledge Base DIALux evo
