Hi,

used together with GI you can get quick results too.

Set the GI up to have tiny little photons and lots as well (1-200000). GI calculates much quicker than FG.

This (GI only) rendered should look like tiny dots (snow like).

Add FG with settings around 100 with min and max really large around 400 and 1600.

this will smooth the Rough but accurate GI out creating a smooth effect that utilizes the multiple bouced light of GI.
