You may want to have a look on this thread here since i noticed you are using pure white in diffuse slots:

Is the problem that it takes more passes to render one of the crops? It might be natural, since there is more GI further away from the windows, which is more difficult to compute

-Put the portals into windows, it will help a lot in this scene
-Are you using HD cache?
-The noise looks like standard GI noise in only indirectly lit portions of the image, i.e. no bug here
-There are no daily builds right now, A5 is the most current one

Thx Ondra.
Yep PT+HD.
Polymax from this forum say me put portals.
And he reccomend settings for interior.
With portals and corrected settings.

Ok, so how about sharing what settings you used in last render? :)

I'll ask PolyMax.
In fact it's default settings.
The whole point of albedo materials, and of portals in the windows
CoronaSky - default settings

So if you set MSI to 50, there will be much more noise?
