Hi,
from 2020.1.5, you need an Nvidia driver greater than 451.00 that is based on CUDA 11.
You have 442.92 installed at the moment that is based on CUDA 10.2, so it is normal to receive that error message.
Please perform a clean installation of the latest Nvidia Studio driver, then download and run the new OctaneBench 2020.1.5, to check that everything is working correctly with the new driver:
