flickering in animation

[chocolate]

Hi everybody!

i'm working on a walkthrough animation and get still getting flickering after trying all the methods explained in so many tutorials about it.

these are my settings:

Irr+Lc pre-calculated (Flythrough for LC and Incremantal add to current map for Irr)

the fact is that in my animations, when objects are far from my camera i get flickers and for near objects it's just small flickers.

I would like to know if this is normal. or what could be the parameter which must be modificated to reduce as much as possible flickers. (GI, Camera, Sun or what?)

Please any help will be more appreciated?
