Iray Scene For Time Benchmarks
By SickleYield
11K Views
This uses items that came with the DAZ Studio 4.8 Public Beta and the Genesis 2 Female Starter Essentials. Please make sure you have both installed before attempting to use it. The "set" is just a primitive cube expanded to a large size and given an Iray shader. There are many materials here that are refractive, emissive, reflective, or use subsurface scattering. They're based on DAZ's included Iray shaders, though I have tweaked the colors more toward the blue end to avoid loudly clashing green and red things in the scene.
I've tweaked the materials on the outfit as well, and added translucency to let light show through, but it's still using only the textures that were included.
If using CPU only or older cards, delete sphere 8 and sphere 9 (the two blue ones to G2F's left and right). They have strong SSS in their materials, and Iray is lagged by SSS where it is not lagged by reflection or refraction.

My time benchmarks for a 400x520 (small) image size at the included render settings:
CPU only 1st machine (Intel Core i7-5930K 3.5 GhZ, 6 cores): 16 minutes to reach 90%, 22 minutes total
CPU only 2nd machine (Intel Core i7-4700MQ 2.40 GzZ, 4 cores): 27 minutes 47 seconds to reach 90%, 1 hour 22 minutes total
CPU only 2nd machine (Intel Core i7-4700MQ 2.40 GhZ, 4 cores) on modified scene without spheres 8 and 9: 14 minutes to reach 95%
GPUs only 1st machine (Nvidia GTX 980 x2, GTX 740 x2, all 4gb cards): 3 minutes 30 seconds
(I haven't yet tracked down drivers for Machine 2's GPU that will work with Iray in Windows 7, so I was unable to test that single GPU with it as of yet.)

It's strange so I thought I'd comment. A year ago the fastest render was with GPU and OptiX at 2 min 46 sec. A year later, the same computer (HP Omen 900X), My best is 1 min 45 sec with GPU only. Maybe there was an update to DS or Nvidia that accounts for cutting the time almost in half? I just noticed the post above. I guess DS is part of the answer
Hi,
Gave up on trying with older laptop, as the new machine has arrived.
Finally spoke to a decent nVidia chat assistant, and pointed me to 'best' driver to install.
So, now have benchmark test image set up on new system, and also added DS 4.12 for comparisons.
Only time to do a quick test so far but have the following times for GPU only:
DS 4.11 - 1 Minute 28.67 Secs
DS 4.12 - 0 Minute 55.88 Secs
Will look at CPU only [and combos] when little more time.
At least now Iray is working properly with GPU, and not dropping out randomly.
Now, if we can just manage to [somehow] get Win 10 to free up Max Vram - luvely jubbly...

Well, as a basic startup there is this:

Hi,
Some good info there. Thanks.
I have only installed on an older laptop at present [msi, 64 GB Ram, GTX 670 card, i7 4 core] Only had time to check basic spec, and a quick run to see if it found the scene OK, and attempted 'quick' render test.
Had to end it at 85% - but that was over 20 mins
]
Not sure if all settings at optimum - do you have a set list of setting that you all use to get a standardized set of comparison times?
Not holding out too much hope for this system - but my new system should thrash it when I can get all settings set up - when it arrives.
Cheers for assistance

Daz Studio Public Beta 4.11, stock scene, no config changes other than Optix and rendering device
Intel 9700K + Geforce RTX 2080ti
Time to 100% completion
------------------------
GPU Only, Optix Off - 1 min 23 seconds
GPU Only, Optix On - 1 min 6 seconds
GPU+CPU, Optix Off - 1 min 26 seconds
GPU+CPU, Optix On - 1 min 7 seconds
The 2080ti is a ZOTAC GAMING GeForce RTX 2080 Ti AMP, i.e. a mild factory-applied overclock to 1665 MHz boost, system is otherwise non-overclocked.

Stock scene as downloaded, unmodified. All times are to full completion.
GPU Only 1 x Geforce RTX 2070 = 2 minutes 21.14 seconds (Optix off)
GPU Only 1 x Geforce RTX 2070 = 1 minutes 49.11 seconds (Optix on)
GPU Only 1 x Geforce RTX 2070 + 1 x Geforce GTX 970 = 1 minutes 45.78 seconds (Optix off)
GPU Only 1 x Geforce RTX 2070 + 1 x Geforce GTX 970 = 1 minutes 19.47 seconds (Optix on)
All to full completion. My 2070 is the MSI Armor, i.e. non-binned chip at stock. When I benchmarked before with just the 970 I didn't get any benefit from Optix. It made little to no difference. With the 2070 it appears to.
