Regard3D is really good for free software and is available on Mac. I'm just not sure if it uses GPUs because from what I remember it seemed a bit slower than other software.

Cool, I personally can't afford 128GB of RAM, I've got 32GB to work with which I'm often close to filling.

Right... but not every user wants to bother with that, and don't enjoy it. For example Regard3D is what I tried to compile on Manjaro a couple years ago and wasn't having a good time doing. Seems like there is no issue if you've got a debian based system? Feel free to take a look at my experience from back then, perhaps you can tell what was wrong since you're much more experienced and comfortable with compiling projects that aren't straightforward and you enjoy it.

By all means, if you feel up to it, setup Manjaro install, and get that software working. Maybe it's a better experience these days, or maybe you run into the same issues I did 2 years ago.
You can see many others chiming in also having trouble. So this is an example of where Snap/Flatpak would have been really helpful by making that devs software more accessible to the community that wants to use it on linux.
If you want to lend your expertise by getting a working build that you can actually package into Snap or Flatpak for the benefit of others, there's your new challenge for fun and learning? You get to help out the Linux community in return, giving back :P
As far as I know, the best free software available that does not require CUDA is regard3d. It's obviously not as fast as CUDA enabled software, but I really like it a lot. If you have the money and CUDA hardware though, I'd use 3DF Zephyr instead.
