Is there such a thing as 'best render settings'?

I have a GTX 1070 8GB & I want to know are there ideal settings for me to render images out at 1080p? Should I enable post denoiser, etc? I understand the basics, but definitely not the in-depth stuff.

A lot of what to do is based on the image and what's in it. Darker images will take longer, but you can improve on that using more light in the scene and using Tone Mapping to darken the render. Anything with refraction, (glass, water, gemstones, etc.,) may need more time to for the caustics and reflections. The denoiser will clean things up early on, but if you let the image render long enough, it will make no difference. (I'm talking about the denoiser built in to Daz Studio.)

What I do for any scene, though, is set Enable Quality to Off and Max Time to 0, (zero.) With quality off, the algorithm stops trying to converge the image, and will stop if it reaches the Max Time or Max Samples. Then you essentially turn off the timer when you set Max Time to zero. That leaves just Max Samples to tell the program when to stop the render. I have a GTX 1080, with 8GB, and I my default Max Samples is 15k. But I will also stop a render if I don't think it really needs to keep going. I'd say most of my latest renders have gone from 2500 to 8500 samples.

I hope this helps, at least a little.

Also go into Render Settings>General and look for the drop down that says Active View Port or Custom maybe (not sure what you have in there) but in that drop down menu there are parameters set for things like HD or Ultra HD. As L'Adair noted, it will extend your render time but i do find they extra time is worth the more crisp looking image.

Other than the latest updates with the denoiser, the very best explanation of the Iray Render Settings pane I've found is this 3-hour long archive of a live stream.

Something to keep in mind about "ideal settings" is that they very much depend on what's in your scene; materials, lights, number of objects, camera position, etc. What works in one scene might work differently in another — don't think of it as "One True Setting™" that you can slap onto every scene. Once you've gone through the tips and tutorial above, think about how they apply to the scene you're working on, and tweak the parameter values until you get a render you're happy with.

So I read this n thought it might help me as my renders where coming out grainy even after 4 hrs rendering. So I tried what u said n now my renders come out white, like super super over exposed n u can barely see the figure. What did I do wrong?
