Wow awesome renders!
It seems that volumetrics rendering with cuda are broken in the E_cycles_2.83_v20200521_lin version.
Here a test scene. ecycles_05_21_volume_bug.blend (1.1 MB)
For me most of the meshes renders pitch black. With optix or cpu it renders fine.

Have you set up correctly volumetrics denoising in compositor?

Yes, it also happens in the viewport. It works correctly for you?
Havenāt tried it since I donāt have 2.83 installed. It just sounded like a very common mistake, so I mentioned it.

Itās all good, E-cycles was a tax write off and I more than made my money back with it doing side rendering gigs. So no need for a refund or anything!

I am able to use optix with an 1660 super and the RTX build. it is about 20% faster. how is that possible.

At some point they made RTX features work with GTX with a minor speed boost!
Viewport rendering is faster (about 40%) in all my tests with E-Cycles RTX on GTX cards. For final render, some scene are as fast or slightly slower, other scenes indeed get a 20% boost with GTX cards on the RTX version compared to E-Cycles standard/CUDA. I donāt advert it until I get a solid 20% boost over all tested scenes and I like to offer good surprises
New builds of E-Cycles 2.83 and 2.90 are up:
- include 2 new splash screens, one for standard and one for RTX
- the SSS passes are now removed like in official 2.83 to ensure 100% compatibility again.
- a bug with volumes and gradient texture was fixed
- denoising is faster in scenes with SSS
- includes all the latest improvements of upstream
If you want to have nice caustic which converge pretty fast, I recommend to have a look to Hans Chiuās node setup 
Of course, it works with E-Cycles too.

New builds of E-Cycles 2.83 and 2.90 are up:
- fixed: the AI-Denoiser could give a white compositing after the SSS passes removal.
- 2.90 now offers the new sky model from @MarcoPPavanello as an experimental feature, thank you Marco!
- E-Cycles 2.83 build for Mac is already available too!
Happy rendering!

E-Cycles RTX 2.83 indeed has much faster viewport denoising now

New builds of E-Cycles 2.83 and 2.90 are up:
- the layout of the AI-denoiser panel was improved.
If you are ok with the contrast of warnings(the last remaining bug planed to be fixed for 2.83), the current E-Cycles 2.83 builds are already like the stable ones!
Happy rendering!

Petra Mikulicic is creating really nice archviz renders. She explains how she did the caustics in her last render, I recommend to have a look

Elpfx did a very nice product visualization with E-Cycles 2.83 too

It is amazing. The detail I got in dark room with 64 samples is simply mindblowing.
A question. I see there are new sampling methods. Should we use Dithered Sobol for best results? What about Progressive Multi-Jitter? And about AO. Is the default distance 1 meter?
