Troubleshooting Weird Performance Issue with DAZ Studio 4.23

stga

I am having a truly weird performance issue with 4.23.0.1 (System: Windows 11, AMD Ryzen 9 5950X, 64GB RAM, NVIDIA 3090).

When I start DAZ, I see an almost 5 minute delay in the startup where nothing is logged:

Furthermore, whenever I touch the render editor pane (with iRay enabled), or do an iRay render, I see a similar extremely long delay which is REALLY impacting my productivity.

I have tried, as it did look like it only happened when I touched NVIDIA code:

1. Upgrading the drivers (currently running studio 565.90)
2. Uninstalling, cleaning out everything I could, and reinstalling DAZ and my entire content library
3. Upgrading the driver with a clean install

Nothing worked.  If anyone could advise on how to troubeshoot this better, I'd love suggestions.  Thank you/

People have  reported problems with the latest NVIDIA driver. Try rolling back to a previous version.

Thanks, will try.

Wow - yeah, that was it.

Thank you!  The load time went down to under a minute, running drivers 561.09.

It seems often to be best to stick close to the minimum required driver version, assuming nothing else on your system requires a newer driver.
