    You are right. I was not expecting differences in the resulting images.

    Did you expect you need to alter your scenes after upgrading to the next major release to get the same results?

    With a benchmark scene if there are significant changes to the way the renderer works, then yes I would expect I'd need a new benchmark scene for a new version of the software. While there haven't been a great many changes to the renderer in LW2020, they are very definitely significant ones that affect render times. So a new or at least revised benchmark scene is needed here.

    P.S. Just ran the benchmark on this PC and it took 15Min 59s which is around 50% longer than it took using LW2019. So something is clearly not right.

    I got myself a new workstation... should update my signature with it when I get time to do so...

    36.6 seconds... Threadripper 64 cores / 128 threads... I recorded a video of it as well.

    I had a pretty good feeling about my 16 core Ryzen. Not anymore. Thanks.

    Right. The first obvious difference is that in 2020 you need to add a gradient backdrop and an Environmental Light. Then, as the Global Illumination model changed and there are other noise filter options etc, the render parameters should be changed.

    I did that and managed to have what looked like the same image but with two distinct differences in two of the objects.

    I checked and found that those objects are the ones with Subsurface Scattering. Principled BSDF changed and before there was a parameter called "Subsurface Color", now it's called "Subsurface Scattering" and behaves quite differently. I didn't manage to replicate the same effect, but I really didn't try it for long.

    I find it very curious that my video of using the top end of CPUs, makes the people visiting my video do a thumbs down.
    I mean... they are essentially disliking all forms of CPU renderingn, no matter what renderengine you use. Which to me is a big wtf moment.

    I mean... Without CPUs, we wouldnt even have computers that works.... LOL

    FWIW, when I checked out your video, the sound was very low, even when I made sure the video volume was cranked up and I smashed the Volume Up button on my MacBook.. maybe just my hardware . . .

    I didn't build it myself, the company I ordered from did that.

    Yeah... I didn't check the video before I uploaded it... my mic is superlow.

    ... which is ~ a grand less than what I paid last year for my system, to give things a bit of perspective, and perhaps a little check-up on ol' what's-his-face's law.

    Hi VirtualFM,
    Could you please share your modified scene for LW2020?

    It was not even possible to see the complete scene in layout because two objects were only visible in wireframe mode.

    There is no 2020.1, only 2020.0.1

    But you should use use 2020.0.2. That one has fixes/speedup optimizations comparing to 2020.0.1
