Is Out-of-Core support not working in 2020 (octane)

[pixelsmack]

I keep getting the same issues. Octane errors randomly. it's using 9GB of my 11GB. Then sometimes it gets through a bunch of frames and then sometimes it only gets through a couple. What REALLY odd is I have another scene that's TWICE the size of this one and it renders. Same exact content, just double of everything. So I don't even think it's a ram issue.

What Nvidia driver do you use?
After I installed the latest NVIDIAdriver,latest Octane 2020 and LW2020 all my problems like this disappeared.
I also had smaller scenes that would crash like this, and bigger scenes would render..and really huge scenes crashed again.
None of that anymore after all the new softwareversions.

I’m using the latest Studio driver. Which is quite out of date from the normal driver. What driver are you using?

[hkleton]

Studio Driver 442.92 , 16/4/2020.

I think that this problem doesn't come from the lack of memory. It sounds to me like a bug or something like that. I'm still trying to reproduce the problem with the other scene.

Thanks,
