Sorry I couldn't get back earlier, had a full day today. To answer your question, here are my specs:
CPU: AMD Radeon 9 3900X
RAM: 32GB Corsair Vengeance 3200
GPU: Nvidia GeForce GTX 1650 4GB GDDR6
OS: Windows 10
Primary Drive: 1TB M.2 SSD (Gen3)
Dedicated 3d Application and Resource Drive: 1TB M.2 SSD (Gen3)
I know what the limiting factor in my system is, it's the GPU. I am and have been very well aware of this fact, but when my 2080 died, this was literally the only one that I could find anywhere near retail, and it was pure luck that I found it back in December. Now that prices are coming down, I do intend, eventually, to grab a 3080 or 3080 Ti, as I only buy PC components from reputable and known dealers, not random people charging 2.5x or more retail and not being guaranteed to even get what I paid for, as has happened to several people I know.
In case anyone is wondering, if I just load a single figure into a scene, and put a non d-force hair on, no clothing, then it'll run the render on the GPU, but only the first render, after that, the VRAM isn't fully cleared, and every subsequent render fills up the VRAM, forcing it to slide over to a CPU render, which takes for freaking ever. It seems that Daz Studio uses a minimum of right at 4GB of VRAM when using iRay, and doesn't clear everything after the render is finished. I've done everything that I can think to do, and everything that I have read to do to help alleviate the problem, but none of it works. This, is why it takes so long for me to render any kind of actual scene, it's using CPU render instead of GPU render.
Also, to answer the question about the image size, it was 2560x1440, as my friend wanted it for a native res background.
