OTOY Forums

Had to re-install windows recently, and after that Octane keeps giving me errors. This happens on any scene, can be simple with no materials.
Windows 10 22H2
Using nVidia studio driver v 555.85.

Hi,
please make sure to have installed c4doctane 2022.1.2-R4, this is the latest stable version for 2022.1 series:
viewtopic.php?f=85&t=81989

Then perform a clean installation of 552.22 Nvidia Studio driver:

To perform a clean installation, please follow these steps:


After rebooting, try again with the same scene and report back, thanks.

Thank you, Beppe!
Followed your detailed instructions and Octane now seems to work fine. So far so good.
Should I stick to this version of nVidia Studio driver?

Yes, it seems that 555.85 version is giving stability issues, better to stay with 552.22 Studio version.

ciao,
Beppe
