Iray Starter Scene: Post Your Benchmarks!
This requires the Genesis 2 Female Starter Essentials and the DAZ Studio 4.8 Public Beta with the Iray content installed. It should require nothing else.
If rendering CPU-only, or on a single older card, delete sphere 8 and sphere 9 as in the second scene shown. Iray is not slowed down much by refraction or reflection, but it is slowed down considerably by high SSS, and these spheres use versions of the "wax" and "jade" shaders DAZ included with the Iray Uber Defaults.
Here are my own benchmarks with this scene, at the suggested 400x520 render size and the scene's included render settings. All are on 64 bit Windows 7.
GPUs only 1st machine (Nvidia GTX 980 x2, GTX 740 x2, all 4gb cards): 3 minutes 30 seconds to finish
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 GhZ, 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: 8 minutes to reach 90%, 14 minutes to reach 95%
I do not yet have Iray-compliant drivers for the second machine's GPU (Nvidia appears not to appreciate my desire to use Windows 7 on my laptop), so I was unable to test that one.
