Nor can I produce the same image twice in a row, PERIOD, if I do not use irradiance caching.
They produce different problems. With IC, I get corner artifacts and variations in luminance. Without IC, there is general grainy noise everywhere.
It's all a question of visibility - hiding the problems. You cannot make them go away unless you buy a much more capable renderer and you allow it to spend 24 to 48 hours per frame. This is why Pixar does not use IDL to make a movie.
Use more direct light and you'll see it less. Use more busy textures and you'll see it less.
On the other hand, as in this render, if you use smooth white objects, with or without IC, and strictly light using IDL (envsphere) you will never get the same image twice.
Here is first render.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
