Hi bverde84,
Quadro A4000 is an Ampere GPU so, the only solution is to install an Nvidia driver greater than 456.38, and run Octane 2020.2.1 or greater, with updated Otoy licenses.

I program CUDA applications. My own CUDA programs written for CUDA 9/10 work absolutely fine without having to recompile on my RTX3090 with only the CUDA11 SDK installed! You can download nVidia's flex physics demo app an example that uses CUDA9 and it works fine on my RTX3090. And you can also see this described in nVidia's documentation on backward compatibility: https://docs.nvidia.com/deploy/cuda-compatibility/
You are either doing something strange or purposely obsoleting prior versions for no good reason!!!
Support your software, and fix this, and stop providing misinformation to customers!!! This is terrible!

I've been supporting Octane since v1, you are far past being a struggling startup, and you present yourself as very bad investment now as you don't support customers properly with this kind of behaviour.
I'm incredibly suspicious as now you have an OSX Metal version of Octane which isn't going to be using hand coded SASS is it. If you have mostly used backward compatible CUDA C++ than it should only be a relatively simple recompile for a new SASS binary. Even if the recompile resulted in an Octane that isn't as fast at least it would be properly supported like that.
From your replies on the forum you have made it seem like it's nVidia's (which I am sure they won't be happy about) rather than your own fault from the bad technical choices you have made.
Paying another 499 Euros to upgrade is not really attractive at all. Because you will just do this again won't you.
