**Hi YK3D**

I remember that Ryan Spaulding (another pre viz architecture guru) had a large thread whilst exploring the various render options, which you might be able to search for here.

Philippe Bouyer of Belino.net posted some of his tips for removing flicker in animations- i'm attaching his suggestions, but the main trick is to Remove Texture AA. and Boosting Object AA.

In my own efforts, I find that less is more, and that it is often easy to get tweaking too many parameters at once, so I often hide everything else from the render and just concentrate on one object to better understand each incremental change I make.

Good luck - do let us know how you get on?

Kind regards
