Hi guys,

I'm using Karma for some creature rendering involving fur. It's incredibly fast but at some point it startskicking up the following errors and the render speed drops dramatically.
I have the latest drivers.
Restart does fix it but the problem does return.
Any suggestions?

Apologies. I did a clean driver reinstall through geforce experience and it seems to have resolved the issue thanks!

No I'm lying. The issue persists.

So dropping the body fur density attribute from 1 000 000 to 800 000 seems to get the render going. Is this a gpu memory limit of some sort? Is there a way to monitor or manage gpu mem usage in karma? Other than keeping an eye on the task manager, which doesn’t seem to be hitting its limit, is there a way to get some other error info?
Btw it seems to be with this one particular fur object. There are multiple others (mane (which also has 1 mil density count), face, whiskers, chin etc) and they seem to render fine.
