System low on RAM:

[Darawork]

Hi,

I've been getting this error for a few years now, as I only have 64GB of RAM on my workstation. This wasn't ever 'that' much of a problem as it would usually render out fine, just a bit slower.
That was using Corona Render 10.

Now I'm using Corona Render 13 (Hotfix 1), and when the RAM runs out, the rendering seems to go very, very slow.
I also noticed that my HDD D:Drive is being used for the Page File (This might have been done by IT here for some unknown reason) and it goes to 100% usage (Read speed 1.3mb/s Write speed around 2.0mb/s). Ideally I would prefer the Page File to be set for the System nVmn SSD, as this might be a bit quicker to read/write.

My question: Has something changed the way the system paging is working behind the scenes from Corona 10 to Corona 13?

I have increased the Out-Of-Core limit from 100GB to 250GB with the default 10% Drive remaining parameter unchanged. This doesn't seem to make much if any of a difference.

Hopefully I'll be getting a newer Workstation soon, with a decent amount of RAM, but for now I'm stuck with 64GB.

86.5 GB of virtualized* RAM used by Corona + 3ds Max
102.9 GB of virtualized* RAM used by all running applications
63.7 GB of physical RAM installed on system
171.7 GB of virtualized* RAM provided by OS

* virtualized RAM means physical RAM + swap file on HDD/SSD

Corona RAM usage breakdown:
747.8 MB used by render elements
31.7 GB used by geometry

Best Regards :)

Hi,

The paging file is managed by Windows automatically, not by Corona. We recommend keeping it set to "System Managed".


If you’re running out of RAM, the best first step is to optimize the scene. If you feel the same scene in Corona 10 uses much less RAM but in Corona 13 HF1 the RAM usage is drastically higher, please open a support ticket and share a short screen recording so we can review the comparison clearly:
