All i can say is that i love iray completely and i have never seen such quality with such speed . It's just a matter to tweak a few settings and the renders are super fast and they can still look awesome , certainly decent enough for animation renders.
I need to ask some questions to those who are the experts in Daz Studio but it will be hard for me to phrase it . Can daz studio handle a lot of objects at once and can it also handle outside landscape scenes with clouds , skies, mountains , cities, buildings . ?

Define 'a lot of objects'...because while Studio can handle quite a few, Iray is limited to the amount of memory on the video card for GPU rendering...which basically means fast renders are not going to happen with a lot of objects in the scene, as it will be too large to fit in the video card's memory.
the only limitation is your imagination!
...and the limit of RAM on your GPU to contain the scene, that plays a huge factor in this, far more than the imagination part.
You can't add more RAM to the card by buying additional cards right now. It is a limitation of Iray. The most RAM you have on one card is the limit of all RAM you have for a scene. a 2GB GPU and a 4GB GPU equals 4GB GPU RAM at render time but all the cores from both cards provided the scene does not exceed the total RAM of a single card so in this case a scene with 2.01GB RAM necessary to render would drop the 2GB card from assisting any part of the render.
Just remember that you CAN render bigger than that, it's just slow.
But still not that slow compared to trying to do something on par with, say, 3DL or other renderers. When I was trying to get as realistic as possible in 3DL, I was seeing multihour renders.
Iray, in CPU mode and 3DL with proper shader set up should take about the same amount of time to render...if that means multi-hour for one, then the other should be the same. Iray's biggest advantage is GPU rendering.
Compositing is your friend and can save you loads of time.
MJC: Yep... that's what I was trying to say. ;)
When most people say 'Iray is slow,' I find it's usually because they never tried to push 3DL toward that level of realism.
(OH GOD GOD RAYS UGH)
I don't buy it. Try rendering hair to the same level as Iray or even LuxRender and watch 3DL crawl.
I love Iray, but if you have a ton of geometry, it will slow down your render or even crash DS if you don't have enough memory. For most things, I was fine with just 16 GB of memory in my system and I didn't hit a problem until I had a highly intensive scene set up. Then I crashed DS because I kept running out of memory. Going up to 32 GB fixed the problem. My problem scene had several figures with LAMH geometry, the Iray Worlds Skydome, Winterland and Above the Fog in it. I could have handled all of those individually, but added up, it was too much for my system at 16 GB. Most people wouldn't have that much high intensity stuff in one render. Luckily, the price of memory has come down and I had been thinking of getting more anyway. Just something to keep in mind. I think the results in Iray are worth the effort. I run CPU only, too, as I don't have CUDA cores or whatever the nVidia cards use. I have no idea if having an nVidia card would have made a difference in my scene and not crashed.
Probably not, as you would be limited to the memory on the graphics card. Iray does some optimization before handing the scene to the card, but if it crashes on 16GB of system RAM it probably wouldn't fit in GPU RAM.
Good to know. Of course, memory was a whole lot cheaper to buy than a new video card.
So, it was easier to go that route and see if it made a difference.
I love Iray, but I've taken a hard turn back to 3DL with more stylized/illustrated look. Which might do well for my bank account.
Until iRay arrived I was unimpressed with most of the PBR renders I had seen. A few looked good, but most had so much noise that the extra realism PBR claimed to bring was drowned out by the distracting snow. I assume most of the renders I had seen up to that point were done in Lux Render where the person doing it did not have the time/patience to render for days to eliminate the noise. Then iRay came along which could produce noise free renders in most circumstances in much less time, particularly if you have a GPU. After that I got a mid-range GPU card and decided to try PBR rendering, and have never looked back.
I have not spent a huge amount on iRay shaders, as I find you can get pretty good results with the shaders provided by DS 4.8 and a few freebie sets. I have purchased some PC+ shader packs, and a couple of skin shaders from PA's, but even these were optional really. The biggest cost barrier for most I imagine is the graphics card (mine was 250GBP, around 400 dollars).
IRAY(and G3F) made the final switch from Poser to DS. I never liked 3dlight. Without any uber environment light set I couldn't get hardley any render, that looks better than old dirty Poser4 renders. With advanced settings the render times explode into nowhere. Iray renders look so much better and they are faster. That's it. I love IRay.
