QMC primary Light Cache secondary and passes?

[phildlight]

I typically use Vlado's universal settings, (I'm using VIZ07+Vray 1.46.15), and it works great! However, today I switched to a new job and setup the scene, setup the render options as I always do, but when I render, it builds the light cache, then goes through 4 prepasses and just takes forever to render. Usually when I render with the universal settings, it builds light cache and then renders. Speed based on noise threshold for the most part. I've re-checked the settings about 15 times, and it's all right. What would cause it to run pre-passes?

Also, a related issue I have is that when I try to save presets, it crashes Viz. Am I alone in that issue? Or is it just a bug? Thanks.

does any of your materials have interpolated glossy reflections enabled?

that got rid of the secondary passes. Thank you! It's still taking forever to render. I think it's just the complexity of the scene. Thanks a million for the quick response.
