The first image I posted in this thread, "Daredevil," had three lights, a relatively large number of objects off screen (Stonemason's Darkside of the City I believe), and was rendered at 1920 x 1080. That took less than 15 minutes to get to a respectable state. The same scene in Reality / Luxrender would have probably taken 4 or 5 hours to get to that point.
The second image I posted, "Candy Gram!," had 8 lights, a large number of reflective surfaces, one Genesis figure, one Genesis 2 Female, and a fairly large set. It was rendered at 1800 x 1200 in 45 minutes. This same scene would have probably taken 10 to 12 hours to render in Reality / Luxrender.
So I have seen a significant difference in speed.
Yeah NVIDIA VCA on my never will get wish list ..so far I am proud owner of 2x Titan X SC just arrived one hour ago , going to install it tonight and run Iray for a spin among other programs depended on GPU
Don't buy them, rent time on them. LOL.
LOL I hope to the time I can finally use the cloud server what would be much better :p

On a related subject... Has anyone tried the network render option that is listed under advanced? I was tempted to experiment with this last night, but got cold feet.
...I find that Iray in CPU mode renders faster that 3DL with UE. The issue I'm running into is pegging my available memory and the process going into swap mode.
You mean, like this?

...board is a tri channel board so 16 GB will end up being no better than 12. Need a full 24 to take advantage of the memory channeling.
GPU render speeds are hardware dependent and they definitely scale, presuming that your scene doesn't render so fast the hardware you throw at it doesn't make a difference. Please be aware that the numbers presented below are estimates, and depend on many factors, like actual Motherboard in use, bandwidth available, RAM, speed of your CPU, etc. YMMV.
If you have a GT 740 with 4GB of RAM and your scene fits on the card, then your render time is likely to be 2-3x your cpu only speed, depending on your CPU (Note this is a low end card, costing about $100.). Now the same scene with 2x GT 740 cards will be 4-6x as fast as cpu only speed. 4x GT 740 cards (Presuming your Motherboard and power supply can handle 4 cards) and you are likely looking at 8-12x the CPU only speed.
The more hardware you throw at it, the faster it gets. Swap out the GT 740(s) for GTX 980(s), 980Ti(s) or TitanX(s) and watch things really start to fly. (Note each of those cards has more power than the four GT 740 cards combined)
Want to get really silly, or scary (depending on your point of view) throw one or more NVIDIA VCA at a render. (Power roughly equal to 8x TitanX per VCA)
...actually the new workstation design calls for dual Titan-Xs with the provision for two more yielding a total of 12288 cores.
...too bad Nvidia doesn't offer a VCA using Titan-Xs instead of Quadro 6000Ms, would be a significant cost reduction as a single 6000M retails for around 5,000$

Newegg has two 24 gb kits of ddr1600
Looking online where others have asked about using 1600 instead of 1600 oc and they were told that it was not a problem both would work
...board is a tri channel board so 16 GB will end up being no better than 12. Need a full 24 to take advantage of the memory channeling.My OS (W7x64 Home Premium) will only support 16 GB, so even though my MB can hold more, I'm limited by current OS.
Yep. It was a bit of a shock when I realized I had to upgrade to the Pro version to use all my new machine's RAM.
A few first rtyouts...
Must say i love this engine.

...so then why would the Board manufacturer just specify the three types I listed? Part of the time I took to study designing a system was about why component compatibility is so important.
The two overclocked ratings listed were only 1866 and 2000.

...however is your board Dual Channel which can support up to 32 GB?
I too have Win7 Home and will be upgrading to WIn7 Pro so I can get the extra memory.

From what I saw online they said the reason was to show that it supported each one from the base to the OC version
Must have misread
Is this your mb https://www.asus.com/Motherboards/P6T/

Yes and no...
It's best to match all 6 slots, exactly, (6 of the same sticks). But, as long as the timings are close matching pairs (dual channels) or tris (tri channel) works. In other words, you have two sets of three...
Also, it will, if the memory timings in BIOS are set to 'auto' run at the speed of the slower set.

A little more info on this site for oc memory

In that case it is probably no use to me. I thought it worked like Luxrender's slave console. Where I could set up another computer on my network to process.
Not a big deal, but current workflow processes are geared around this anyway.
...this is the one i have (tracked through my order history)

The box is different than the one pictured on the ASUS site (dark blue) Part # 90-MIB720-G0AAY00Z.
Does this include Home Win 8/8.1 as well??
OK, found my answer.. Tom's Hardware forums:
x64 128GB on non-Pro,
x64 512GB on Pro.
x86 of any version is limited to 4GB.
Does this include Home Win 8/8.1 as well??
No, as it turns out. It has limits but they're much higher. https://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx#physical_memory_limits_windows_8
...they are already talking about MBs that list 1600MHz as one of the set memory speeds. Would be nice if I was sure about mine as there is a Corsair 24 GB kit for only 189$.
I wonder if I can find this out in the BIOS Settings?
Does this include Home Win 8/8.1 as well??
...Win 8/8.1 Home Edition supports up to 128 GB of physical memory. Same for the forthcoming Win 10 Home Edition.
No, as it turns out. It has limits but they're much higher. https://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx#physical_memory_limits_windows_8
Yea, just updated my post above yours! :-)
...I get a "Page Cannot Be Found" error. so I just Googled Win 8 memory limits.
For some reason Grandad always looked rough before that first morning coffee :lol:
Trying out G2M creature morphs that are on sale http://www.daz3d.com/creature-creator-hd-for-genesis-2-male-s and the new Edit Hair http://www.daz3d.com/edit-hair-for-genesis-2-males.
:-)
lol !
Hi Scythar,
Some nice renders for a first tryout. I like the beach scene, and the lighting on the "Inside1" render.
Iray certainly is a great render engine. :)
Cheers :-)
