Hey guys,
so I gave it a shot with the high-quality setting and I have to say its pretty awesome already!! There are several things that are super cool with the new progress display, but for bigger projects, the first phase i.e. can get quite long and its not considered in the time remaining…so fairly intransparent. But nevertheless a huge step forward!
Sadly, I forgot to turn off “use normal maps for static lighting” so I got a couple of artifacts. I will do a clean rebake tomorrow, but for now here is a first tease! 
I will upload some more images and stats when I have a rebake and a bit more time If I remember correctly, this bake took around 1h…maybe a bit less 
Cheers!
