Before you convict me too hard, the rendering is almost 20 years old, created in 2001.
3D studio MAX R3 & finalRender from Cebas.
Lit up with a few area lights, real global illumination was unthinkable on my computer back then. Even so, rendering in 1152 by 864 pixels took several hours on my AMD Athlon K7 with a few hundred megahertz and a RAM of 768 megabytes. Graphics card, I do not remember today, something auspicious with 128 MB, if I remember correctly.
I really never finished the project - actually, I wanted to model my whole apartment, but then I lost my enthusiasm when it came to modeling the cables.
Today I have 16 cores with 4 gigahertz each, 48 gigabytes of RAM, several TFT monitors, a NAS with 16 terabytes of hard disk space and some NVMe SSDs for the operating system.
And yet rendering times are still way too high ... now that we're using microdisplacement, global-illumination, area-lights and volume-scattering.
Some things never change somehow ...
