URGENT HELP!!! Iray not working on New System

in Technical Help (nuts n bolts)

I recently upgraded my computer to a new Motherboard & CPU (ASUS ROG Strix Z790-E x1 & Intel 19 13900KF CPU) while keeping my RTX 3070 GPU.  But for some reason it's refusing to notonly render my scenes but also display them in Iary Mode.

Among the log errors I get these

2023-04-01 14:55:19.054 WARNING: ..\..\..\..\..\src\pluginsource\DzIrayRender\dzneuraymgr.cpp(305): Iray [WARNING] - IRAY:RENDER ::   1.1   IRAY   rend warn : GPU 1 (GeForce RTX 3070) with CUDA compute capability 8.6 cannot be used by iray photoreal.
2023-04-01 14:55:19.054 WARNING: ..\..\..\..\..\src\pluginsource\DzIrayRender\dzneuraymgr.cpp(305): Iray [WARNING] - IRAY:RENDER ::   1.1   IRAY   rend warn : There is no CUDA-capable GPU available to the iray photoreal renderer.

And these are the warnings I get when I try to render a scene

2023-04-02 18:04:29.232 WARNING: ..\..\..\..\..\src\pluginsource\DzIrayRender\dzneuraymgr.cpp(305): Iray [WARNING] - IRAY:RENDER ::   1.0   IRAY   rend warn : The 'iray_optix_prime' scene option is no longer supported.

2023-04-02 18:04:29.248 Iray Render error: Invalid parameters (NULL pointer).

I've attached a copy of a log file of the start up on Daz & a log where you can see the errors.  I do need urgent help with this as if I can't get this working again I can do my work

    What version of Daz Studio are you using, and what NVIDIAgraphics driver version are you using? Your log file says the 3070 is not compatible with the version of Iray you are running. You probably need to update Daz Studio or the driver or both.

    You left the DS version out of the log, but judging from the Iray version (July 2019), you need to update Daz Studio.

    My 3060 is running fine with DS 4.15.0.2
