While the speed is definitely not anywhere near the old Art•Lantis, considering the radiosity, it is lightning fast. Quality wise, no comparison ...
A little clarification ... I assume that Djordje and I are talking about the same thing.
The speed of "R" is
faster than 4.5.6 for
exactly the same settings (e.g., no radiosity). Apples to apples. An interior scene I have that rendered in 1 min 45 sec in 4.5.6 renders in 1 min 30 sec in "R" (900 x 1200 pixels). This has 9 lights and a heliodon.
With 7 of those lights checked to 'contribute to radiosity', and with radiosity at the 'low' setting, the image renders in 3 min 19 sec. Still pretty fast, but of course turning on radiosity slows it down.
A few other observations. Bringing 4.5.6 file into R, the lighting of the scene is not the same, as the light intensity values seem to have been redefined. (The scene is less bright.) The easiest way to get things looking similar is to turn on 'ambiance' in R - the brightness of which is chosen via a color. For neutral ambiance adjustment (brightness), use a grayscale (right mouse the color swatch).
Comparing the two reminded me of another long time wish from 4.x that has been realized. 4.x always used 100% of the CPU even when idle, making laptops run hot with fans blasting. "R" behaves like a normal program, being idle when idle.
