or journalistic and similar purposes often at least two different sources confirming the issue are required.
I had a very hard time finding any other sources publicly acknowledging this issue.
Finally, on the DAZ3D forum a user called garyh.pub pointed out that Nvidia Iray provides some information about available VRAM in the DAZ Studio log file as well.
"Help -> Troubleshooting -> View Log File...
Search for "GiB available" in your text editor"
Test setup:
- 1x GTX 1080 set as display only
- 2x GTX 1080 Ti set as rendering devices in the DAZ Studio Iray Render settings
- Scene: 1 cube primitive and Nvidia Iray live viewport active.
Result in the log file:
"2017-05-28 06:01:31.567 Iray INFO - module:category(IRAY:RENDER): 1.1 IRAY rend info : Your NVIDIA driver supports CUDA version up to 8.0; iray requires CUDA version 8.0; all is good.

-> The values about available VRAM indicated by Nvidia Iray are similar to those indicated by Otoy OctaneRender.
