No, it's just that when we released Arnold 5.3.0.0 only the creator drivers with the proper optix support were available. We mentioned creator drivers to make it easier to find the latest (at that time) driver version.

Can you give the latest nvidia driver a try? As of right now I believe that's 430.39. You might need to look under game ready. While I don't have a 1660 to verify, I think this driver adds support for your card.

There's currently a driver bug for those Turing but non-RTX cards, this has been reported to NVIDIA and we should hopefully get a fix in an upcoming driver. I've updated the supported GPU page with this info: https://docs.arnoldrenderer.com/display/A5ARP/Supported+GPUs
