on how to fix or improve it...

Thanks a lot !!!

yep, looks like the old-classic-GI-flickering-problem! I dont use Brazil, so I cant really point you towards any settings. Suffice to say the most likely way of getting around would be :

A- sample more, until the flickering becomes too small to see

or

B- use a non-adaptive GI algorythm, so the samples are not psuedo random. Its the randomness of the samples that causes flickering like that, because the hemispherical rays shot from each sample (with monte-carlo GI) head off in different direcions each frame.

Looks like a sampling issue. You know, you really should post this question to the Brazil forum. I guarentee you'll get a response, probably from the developers...
