Hugs to LadyElf, nice to see you!

I have a 4070Ti. I don't think I did anything special for setup. BUT ... in the Render Settings dialog under SuperFly there are rendering presets (click the Load Preset button and you should see them listed). I usually do final renders with OptiX High (there's also an Ultra Caustics setting but since I typically do portraits I rarely need that). You'll see lots of little "fireflies" and noise with the lower default settings. The high preset takes care of that.
