Here is discussion about OptiX Prime Acceleration:

It's a little more complicated there. Since version 4.12, DAZ gave this issue to the graphics card itself, which actually caused many users to think about buying the expensive RTX 3090, because their old scenes are no longer fit in VRAM of their old videocards.

And yes, 'it's always on now', DAZ is not optimized for this parameter since version 4.12. I'm wrong about that (as always, I should have checked it myself rather than take others' word for it).

I read through that old thread from 2019 and I had to laugh, too much guessing not enough knowing. Sample size in that thread is just too small to draw any conclusions of whether or not OptiX was an issue.

VRAM was always an issue with DAZ as it does almost no scene optimization so as a scene creator you always have to watch what is in your scene or use one of the third party utilities to reduce the poly count. OptiX forced all scenes to use more VRAM than pre-OptiX. I was previously using a 1080 Ti, with 11GB of VRAM there were few scenes that would not fit in VRAM.

Also note that DAZ doesn't pick and choose which features of Iray they want to use. Nvidia created OptiX Prime to benefit from RT Cores that would help nudge people to ditch the Pascal based, Maxwell based and older GPUs for the newer Turing and now Ampere architectures. Daz just uses what Nvidia gives them. With OptiX Prime being the basis for the current iteration of Iray, the OptiX stuff happens at a lower level without any intervention by Daz or any other application that also uses Iray.

On another note: (Adding this to maybe help others with the issue I was seeing)

I think I will be back to rendering a few scenes here shortly. I had some issues trying to undervolt my new 3090. I thought I had done all the testing I needed to make the undervolt work, and it does in every game, both AAA and small studios, I tried and all the GPU benchmarks, but when I finally got around to DAZ and tried to render multiple scenes I would get the first one and then all subsequent renders were blank. The Daz forums were no help as too many people just guess and others just complain, but I pieced together that my undervolt was the issue. I had to nudge my undervolt upward until I got DAZ to work reliably. I am finally there.

Plus Daz still has issues with Genesis 8.1 and loading expressions. If you have a a lot of Zeddicuss Genesis 8 packages (I am sure there are other Creator with issues too) the log gets filled with warnings when loading G8.1, the more you have, the more warnings logged and the more time it takes to load the figure. I am using a workaround that eliminates the warnings and it appears to be working. The workaround was to move the Genesis 8.1 alias morphs that are only there to prevent loading Genesis 8 expressions when loading an 8.1 model. They are located in /data/DAZ 3D/Genesis 8/Female 8_1/Morphs/Daz 3D, move both the /Base Pose Head and /Expressions out of that directory and warnings are gone.

Now all that is left is to load all the more obscure morphs into my 'DAZ Junk' library.
