Help Upgrading PC
So I want to upgrade my PC to optimize my rendering speed, when I checked to see if I could upgrade my RAM I found out I can't. Here are the specs for my computer:
ASUS
Model: G20AJ-B09
16 GB RAM
i7 Quad Core Processor 3.6 gHz
NVIDIA GeForce GTX 760
What can I upgrade on this that will increase render speed? Will upgrading the graphics card help with render speed? Is there anything else?

Big question...which renderer?
Daz Studio 4.7
He means are you using 3delight or something like Octane or Luxrender? And are you planning to start using Iray when 4.8 comes out? If you are going to upgrade you need to, in the words of the Joker, "Think about the future."
I may use Iray, I don't know a lot about it. If that was the case, what would I need to upgrade? What are the advantages of the Iray vs what I'm using now, which is 3Delight
It's a different type of rendering. 3Delight is biased, Iray is unbiased. Iray is (in theory) more GPU intensive. 3delight is more CPU intensive. Iray works with nVidia cards only, I think. So if you want to use Iray that may lock in some of your choices.
What does biased mean in regards to a renderer?

Awesome thanks, that was very helpful! So if I understand it correctly, and please correct me if I'm wrong, a biased rendering engine will usually have faster render times but at the expense of quality, usually. I also read that unbiased render engines are not as ideal for animations, which is what I usually do. Is that true?

Ah, ok. Thank you for the quick replies, I think this has helped me reach a decision :)
I'm not sure it's fair to say that unbiased has better quality, as a general proposition. That is really a matter of taste
The primary difference between biased and unbiased is in how naturally they compute the physics of light beams. Biased render engines do not compute all of the bounce and scatter of real light in an atmosphere. It's kind of like how you would see light work on the moon. To simulate atmospheric scatter, ambient light, etc, you need to use multiple light sources, even though in the real world there would only be one or two. So if you are doing sunlight, you may need up to 7 lights -- the most intense, directional light for the sun, but then things like bounce light, overhead light, fill light, back light, and the like. In an unbiased engine, you can just put a sun source in the right spot, and the renderer will correctly compute all that other stuff, requiring less fiddling with multiple light sources. Because they more accurately mimic the real world, and we have an intuitive feel for what sun or light bulbs do in the real world, it is easier to intuit and set up lighting for your scene with an unbiased renderer (at least, in the sense of it being more natural). But I have seen some very, VERY good lighting setups in biased renderers that you would not be able to tell were multiple lights, and look very natural. I am not that good yet, but some folks here are.
So each method has its pros and cons. Personally, I have tried unbiased with Reality/Lux and I find it to be more of a pain in the ass than it is worth, especially with the longer render times. Most DAZ products come with 3delight mats built in, not Lux mats, and you have to futz with every damn mat and surface in the game to get it to look as good as or better than 3delight. For a small scene, it's not a huge deal, but for a big scene like Urban Sprawl 2? OMG, I don't even want to attempt it. To get it to look "real", i.e. better than 3delight, would require hours upon hours of fiddling. Or, I could just set up a handful of standard DAZ lights in 3delight, punch render, and be done in 5 minutes. The choice here is obvious, at least for me.
Maybe Iray is different, I have not tried it... but my overall take on Reality/Lux is that it is not worth the effort. So you should really try both, and see what YOU like. Do not be beholden to what other people like.
Aren't there quite a few products in the store that do not work with iray? I'm not switching over to it and this discussion seems to cover mostly iray considerations. Although it will be the default in 4.8, 3DL will still be available and a lot of us are sticking with it.
Wrong Iray works with any card, but you will only get the fast speed GPU rendering with a Nvidia card and the recommendation is that the card has at least 4GB of memory.
The set up times for Iray are much quicker than Lux/Reality, a lot of textures auto convert very well. Lighting is totally different and is a bit of a learning curve there again its also easy to get a good looking render just using the default HDRI.
