I pump to it a lot more than you think you have on your computer in matter of details and quantities and it (still) works, it doesn't bog at all so I disagree, again. I have a I-7 8700 3.2 Ghz CPU, 16 GB RAM, RTX 3080 Ti 12GB VRAM. I had an older the system , without the new CPU and the new graphics card (with a MSI GTX 1070-OC, 4GB VRAM graphics card and a i-7 3770 CPU) and it still worked as I mentioned before without a flaw on Win 7 x64 and Win 10 64x.
My guess is that something is wrong with... YOUR configuration/computer and not the other way around, but I might be wrong...:)
