The scene renders really fast, and I hope those fireflies go away after time.
In border-rendering tests of the white stripe they vanished at 70 S/px, but I don't know if the full render will behave similar.
I can't use firefly rejection because the displacement already fills my RAM (only 4GB) and Microdisplacement would slow down the renderspeed to much.
My final version is a bit different from this one and baking right now (but if you see huge mistakes, please let me know. Maybe I'll consider a restart).
