Do you have NVIDIA card in your system if, not don't waste your time.
If you're happened to be very new to Daz and wish to learn it, consider the fact that unless your pc has a great graphics card, you will have a lot more frustration than fun creating content in Daz. If your current computer is not specifically designed for digital art creation on gaming everythyng you try to do will be super slow. From opening the program to simulations to even saving your file and rendering. Expect your system resources not being able to keep up with Daz studio demands of the cpu and gpu in your 4 yr. old computer that does not have at least 8 core prosessor or Nvidia card in it. As a result Daz will crash or stop working often.

In DS, F2 > Interface, what is "Display Optimization" set to? Except for Iray GPU rendering you don't need a great video card. I have a 9-year-old laptop, quad-core i7, 8GB RAM, Geforce 525M GPU. Can't do Iray GPU rendering since DS4.10 (and it wasn't much help anyway, with only 96 CUDA cores). I prefer 3delight anyway. It runs fine for everything else.
Iray wants a good Nvidia card; there's no way around that. Get the best one you can afford if you wish to use Iray. I installed a 4GB GTX 1650 and consider that the minimum.
well now you do have the Blender bridge
I have a GeForce GTX 1650 4GB GDDR5 mobile with I think it's 892 cude cores and it it took 2 hours to do a render that my Ryzen 7 2700 with 8 cores/16 threads 32GB DDR4 CPU rendered in 3 hours. So the 1650 was 33% faster than my CPU render but those aren't the sort of numbers that knock your socks off. That is integrated in a laptop so can't be bought by endusers without buying an entire laptop.
Soon I will be adding a 2nd GPU to my desktop computer, current one is an MSI Radeon RX 570 8GB RAM, and that is also a GeForce GTX 1650 Super 4GB GDDR6 and in this case it has 1280 cuda cores with should cut render times down to either about 1 hour or 1 1/2 hours. I think 1 1/2 hours is correct estimate since it has only about 50% more cuda cores than the mobile GPU (1280 cuda vs 896 cuda). This card is a PCIe x16 with one fan but dual slots and goes for $150 - $175 USD. Still nothing to knock your socks off. 5 minutes or less per 4K iRay render is what I consider 'knocking my socks off'.
That said, it is an huge impovement of 12 hours to 36 hours over CPU renders on my old laptop's i7-3630QM CPU with 16GB RAM.

How does Blender work? In your opinion, does Blender render work as well as an nVidia Iray render on DS?
Asking this because if it does, then I might revert to my Mac and not require my recently purchased Dell with nVidia which was specifically purchased for DS+Iray.
Is Blender similar to DS in terms of usage and functions, etc... hopefully the learning curve isn't as steep.
I don't find Blender easy at all
it is however a very robust software but has a difficult user interface
those who master it love it, I am not anywhere near there yet
just mentioned the new free bridge because it might suit some
Just like a Boeing 747 is a lot harder to pilot than a skateboard.... But there is so much more you can do with it. ;)
I had a GTX 980Ti and it was decent. Upped to a 1080TI and noticed a big improvement all around. Next upgrade will be the 3080TI when Daz suppots it and all the bugs are worked out. IRAY rocks! Always go for the most onboard RAM in your card as well as you can afford.
