Ok, here's some interesting developments with beta testing 2023.2...
- Standard and Lumen GI both crash when presented with a high res 8k task as previously posted.
- In order for GI to be totally stable to render, you need to reduce image quality down to 4k resolution and reduce some refinement to the render process. Not max.
- The estimated time to render with GI is horribly skewed and out of whack. It may say over an hour for a few minutes, then look like it's frozen, then boom, render is complete.
- Lumen, as I understand it, was supposed to be a quicker near real time rendering solution. In reality, when you can get a stable render, it still takes as long as a path tracer render and looks worst.
- A new Nvidia driver was released today, however, there's no improvement there.
At this point with my experience in purchasing the update, I'd be cautious about updating anything. This still could be a local issue, however, I'd like to hear from some people if they can pull off any 4-8k Lumen renders with any stability. On top of that, is it outperforming path tracer renders in time?
Note in the attached image below the estimated time for a 4k lumen image render at max refinement. As a reference, I typically render an 8k path tracer image in 8-10 minutes. Note the computer stats in the bottom left and the overall lack of GPU engagement, which is confirmed also by how quiet my GPU is. In path tracer renders my GPU fan winds up like crazy.
