I've tested different settings for a simple glass cube box filled with a yellow liquid.
First tests are material settings without volume.

I've encountered an issue with GPU rendering.
GeForce RTX 2080 Super renders only about 5% faster than Radeon RX 5700 XT (see LuxMark 3.1)
But here the ...

So probably it wouldn't fully work for you on GPU yet.

CUDA is working, which is why I missed this, doesn't show as obvious in all situations

I have a PC with two graphics cards, one AMD and one nvidia. So, I can compare CUDA with openCL directly.

Thank you for your work. Maybe I will setup a test scene in the next days.
Maybe you remember the orange juice discussions a few years ago

great work

Maybe you wish to play around with different Metropolis parameters or Light|Emission performance|importance ..
