Hello,

I'm trying to get RTX turned on in C4D with Octane 2020.1_XB3_R2. When I go into Octane Settings -> Settings -> Device Settings "Use RTX acceleration (experimental) is grayed out. What are the software requirements that I might be missing to run rtx?

Hi,
you need a Geforce or Quadro RTX with Nvidia driver greater than 434.xx, my suggestion is to use Studio driver 441.66.

Thanks Beppe, updating the driver to 441.66 worked - but it wound up increasing render times and causing c4d to hang quite a bit with rtx on and off. So for now I'll be reverting to the old driver I had.

I appreciate the help though!

Which driver are you using now?

Please, download and run GPU-Z:

And share a screenshot from the Graphics Card tab, for all the available Nvidia GPUs, thanks:

I had the 441.66 Studio driver you recommended in your earlier post.

See attached image for gpu info.

Thanks for the help Beppe!

Ok, thanks, please try to go to nvidia control, menu Help, and enable the debug mode, to work with GPUs at default clock: And please consider that 2020.1 and RTX support are still un beta, so some glitches are expected.
