RTX OctaneBench 2019 Preview is based on CUDA 10, while recent Nvidia drivers are based on CUDA 11.
So, you should need to downgrade the Nvidia driver to a version from past year, while waiting for the upcoming new version of OctaneBench with Ampere/RTX support.

We are working on gathering user scenes for a new OB next year that will leverage RTX fully as in this scene. In the meantime, OctaneBench 2020 will be live soon with the classic OB3/4 scenes, with a more modest speed boost with RTX on by default.
otoy should probably update the link on their official octane page to point here https://render.otoy.com/octanebench/ instead of to this discussion thread where people waste time downloading, installing, and running the 2019 obsolete version which doesn't work with current nvidia drivers. 
Here is the page with the stale link
