Hi,
are you working with Standalone or an integrated plugin?
Which exact version are you trying to install?
Please make sure to have updated Win 10 to 2004 or greater, and to have an Nvidia driver installed greater than 456.38.
Then please download and run OctaneBench 2020.2.3, and share a complete screenshot of the result, thanks:
