Interesting developement...
One thing that really had me chuckle:
In the video he demonstrates all these "RT" sliders and you see them update very fast and its all pretty cool.
Towards the end the guy says something like: here you can crank up the samples to get even More ubiased rendering...
To stay in the vein of good old maxwell unbiased snobism (

): How can something be more or less unbiased?
Isn't it this way: either ur engine is 100% unbiased or not?
I understand that you can regulate the quality by calculating more or less samples per bucket or whatever.
To me this would mean: if you crank this all the way up its 100% unbiased, otherwise its like a cheap version of it?
just a little thing I found rather funny
still very interesting to see the developement in this field!
