That only tells you what it started to render with, not what it is actually or currently rendering with, at any given time, through the rendering process, after any iterations. I have had GPUs drop-out mid-render and it switches to CPU, without any mention of it in the logs or in the render-window. Oddly, I also get, on occasion, a notice in the render-window activity, showing specific cards rendering the "Scene update", saying "GPU-0 updated scene", which also don't show in the logs, but they show in the window, as you render. (Usually just before the whole system stops rendering with anything but the CPU, which I have actually told it NOT to do.
Yet another redundant option to select, since it always "Falls back to CPU", instead of just stopping and asking if you want to continue on CPU only, when you tell it NOT to use CPU to render.)įor the record, these are non-RTX cards. (Titan-V and Titan-Xp-Collectors-Edition cards.) All randomly fail, in various rendering situations. With or without IRAY preview on, or with or without Optix selected, on both the public-release and beta-public. With any of the latest or prior two video drivers.
