It's actually irradiance caching, not IDL, that you're dealing with.
There's no free lunch here. IC is a speedup that you use in exchange for quality, accuracy, and consistency. You decide how "wrong" you are willing to allow the render to be, and you get a big speedup. Since IC is a monte carlo technique, the results are, by definition, random and inconsistent.
If you set IC to 100, you disable it because then you're saying you want the IDL calculation to be 100% correct. You can then use multiple renders to spread the load. However, the load will be hundreds of times bigger.
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)
