Unable to render large scene with Nvidia Studio Driver 441

[hkleton]

Hi,

My extreme big scene does render with Nvidia Studiodriver 431.86, but will not render with 441.66 (studio driver)
With 431.86 I was able to render it, did upgrade to 441.66 to test the RTX performance in Standalone 2020.
Great improvement!
But, now I cannot render my current project anymore.
Had to roll back to 431.86 to get it working again. (that is the only thing I changed, nothing else)

The error I get in the log file when using 441.66 is this:
00:01:49 (0109.85) | ... Init rendering ...
00:02:05 (0125.58) * OCTANE API MSG: Failed to allocate page-locked memory

00:02:05 (0125.58) | +++ RENDER FAILURE +++ processing the failure callback
00:02:05 (0125.58) * OCTANE API MSG: Failed to allocate page-locked memory

Any ideas what might be causing this?

Thanks,
Hans

Yes, this sounds like some kind of issue with this drivers version. Have you tried the 436.48 studio drivers?

Hi,

I only can find 441.66, 441.28, 441.12 and 431.86 and below at NVIDIA's website.
436.48 seems to be gone.

Someone has it laying around?

Thanks,
Hans

I'm was the exact same issue since updating to this driver. After I switched back to 431.86 everything was working again!

Problem with 431.86 is that it's not supporting RTX so it's not an option to "stay" at that version .

So OTOY needs to find reason why is a driver change making large scenes un-renderable suddenly.
Could it be some Out Of Core problem then - No ?

Is this problem related to Out of Core or NVlink memory pooling in new drivers ? I cannot get to work memory pooling from months.

I am having similar issues. Rendering large scenes crashes octane with 441 drivers.
