Some entries, such as the mention of Iray Realtime, Linux, etc, currently have no bearing on Daz Studio itself but are included for completeness. * Note: The entries below come directly from the NVIDIA Iray release notes. A separate discussion thread will remain available ( linked below), but the thread itself will be closed for comment so as to avoid the information being buried by the discussion and to provide notification through regular features of the forum software. To address some of these issues and bring more visibility to the changes for those who want/need it, we now split these posts off into their own thread. This same information would also then be reposted when a Public Build was eventually promoted to General Release. In many cases, while the information contained within the posts was/is useful to those that want/need it, it seemed to go unread by many. Since the release of Daz Studio that followed the initial introduction of NVIDIA Iray in Daz Studio ( 4.8 - initial introduction, 4.9 - following release), a list of its changes have typically been made available in the posts that immediately follow the announcement. meh.When a new build of Daz Studio includes a new version of the NVIDIA Iray renderer, the new build of the renderer comes with its own set of bug fixes, new features, adjustments to existing features, etc. It would be nice if there was a software fix down the road that wasn't going to require all new hardware, 'cause, gosh, I don't just grow money in my backyard, but. But thank you, yes that is what I was thinking and your answer is, if not hopeful, at least enlightening. This is something that would require a chnage on nVidia's end - I believe the newest/forthcoming GPUs have or may have nVlink (or soemthing like that) which at least allows multiple GPUs to pool their memory, though I don't think it gives access to system RAM. However, as yu say any GPU that cannot load the needed data (or runs out of memory during the render) will be dropped - that has nothing to do with utilising the CPU or not.

You can, in the Advanced tab of render Settings, enable both nVidia GPU(s) and the CPU. which seems a bit stingy, all things considered.

While I can handle pretty big scenes, my friend is stymied with scenes with more than two models. I may have been misinformed, then, but I was under the impression that if a scene required more VRAM than my card had (8GB in my case, 4 in the case of a friend's), then the entire scene was dumped to the CPU. CPU effect on the render time is negligible.
