Hi, my tests with LW2018 native renderer. I wanted to try.
8 years old 6C/12T xeon X5680@3,4GHz

interpolated MC - 13m33s

Thanks for tests.
LW getting better and better with Interpolated GI.... for sure is faster and better looking than K2 (K3 I did not test yet becasue G. will add soon new engine for that)
Brute Force in LW is just horrible, forever noise (especially not balanced noise)

Can you make test like in K3?: 40 bounce lights.

Sure, here is 40 bounces interpolated.
The difference between 3 bounces and 40 bounces is very subtle.

Amount of bounce lights should be as much high as possible: 20 recurse is not enough to fill up corners. I mean you can see information cells in precomupte mode but information is poor. Of course you can use 5 recurse (like everybody in LW or other software) but it will produce a lot errors (visible and not visible) which cause for example speed of render. For LW native recurse 5-10 is maximum of technology for brute force (you see how long took render without interpolation) over that amount of calculations raise up drastically in LW (bad optimization).

To see differences just simple use this:

this is is simulation scene which shows difficulty which can be found in interiors with shader surfaces and complex objects.
