New Nvidia driver (418.81) potentially causing issues

TojiroTojiro Posts: 64
in Technical Help (nuts n bolts)

So today I downloaded the latest Nvidia driver, 418.81.  After that I tried rendering something and GPU-Z started telling me that GPU use was at 0%.  I thought it was odd, seeing as how it was just one figure and a 16k HDRI dome.  I tried another scene and the same thing happened.  So then I tried rendering a simple ball primitive and a smaller 2k HDRI dome, but still the same.  I dug into the troubleshooting log and found this:

2019-02-05 21:15:55.827 WARNING: ..\..\..\..\..\src\pluginsource\DzIrayRender\dzneuraymgr.cpp(304): Iray ERROR - module:category(IRAY:RENDER):   1.17  IRAY   rend error: CUDA device 0 (GeForce RTX 2080): an illegal instruction was encountered (while launching CUDA renderer in core_renderer_wf.cpp:437)

Among many many other error messages.  

It had been rendering fine (sort of) before the driver update so I rolled back the driver and GPU usage is back to normal.  I think that something in the new driver update might not play well with IRAY or ray tracing...

Not sure if anyone else has been seeing this, but just wanted to show what I found in case it gets someone else.

    I always wait at least a week before updating the drivers so that potential problems get exposed and, hopefully, corrected pronto. If it is widespread, there will be flak.

    There is another thread already on this subject, so it's not just you. Nvidia Driver Issue

    It definitely caused problems. I had problems and had to roll back a version. Other people reported the same.

    The predominant school of thought is to always keep your drivers up to date. However, with the all-too-common problems that seem to arise from driver updates, I am inclined to subscribe to the "if it ain't broke, don't fix it" school of thought. I suspect that most people do not even bother looking at the available documentation that comes with driver updates that describes what the included changes/fixes actually address. The latter should be standard operating procedure, in my opinion. If there is nothing there that affects you, I would be inclined to forego the update, especially since many of the driver updates for mainstream cards are primarily designed to improve gaming performance. But to each their own, as the saying goes.

    I had same issues with 418.81, I had to go back to 417.71 ...

    CUDA fails to initialize and falls back to CPU render ...

    I installed Octane render 4 and it didn't work so looked on forum and learnt that driver broke it so reinstalled my previous one, you would think they'd make sure iray worked though!

    We are told that nVidia is aware of and working to fix the issue.

    I just downloaded and tested new driver update here, still having issues with CUDA rendering.

    Same issues, same errors, rolling back again to 417.71 ...

    The patch notes for 418.91 says it crashes iray and optix
