I have CUDA 12.2 instaled on a Windows machine but Discovery requires 11.5   What is the safest way to downgrade from 12.2 to 11.5?

Hello Jon, 

I don't think there is need to downgrade. Are you facing any issues while installing Discovery or when opening?

Regards,

Discovery installed aleady.  This is is simply the output from the compatibility checker, I ran it after Discovery failed to start. Discovery 2023 R1 has worked on this machine previously.

Hello Jon, 

I checked with the developers and the issue is you have 2 graphics cards that support rendering, and Discovery is having trouble with the multi-GPU setup.

Please go into Nvidia settings and assign a specific card to Discovery for rendering. Let me know if that helps. 

Instructions:

Go to the NVIDIA Control Panel (by right-clicking on your desktop > NVIDIA Control Panel), go to the Manage 3D Settings tab. 
There, under Program Settings, make sure you Add Discovery as a program that is using the best specs of the NVIDIA driver to a specific one.
