For several days I had been experiencing slow performance with Lightroom Classic. I actually noticed it after their latest update. With all the incorporation of AI that Adobe is inserting this undoubtedly has a performance impact. The past few days I noticed that when attempting to apply a mask that has "Select people", Lightroom begins the process but then seems to hang. I let Lightroom sit overnight just to see if it would ever complete but it did not. Task manager was showing low to no CPU utilization by Lightroom. Also, the only way to exit Lightroom was to terminate it in the task manager. However, sometimes this was even a problem as Lightroom would not appear in the Windows task manager. I had to use another application, "Process Lasso", to find Lightroom and terminate it.

The system is healthy and powerful enough consisting of a 6-core Xeon processor (twelve threads), 128GB of RAM, NVMe SSDs, and an Nvidia RTX Quadro 5000 GPU. This is a Lenovo Thnikpad P-73 Laptop Workstation.

Lightroom is set to use the GPU for hardware acceleration. However, this was not helping either. A re-install of Lightroom did not solve the problem and I also confirmed that it has nothing to do with the catalog size by using one of Scott Kelby's catalogs with about seven photos in it---the issue persisted.

Final fix was to go into the Nvidia control panel and switch the GPU from "Dedicated to graphics tasks" to "Use for grahics and compute needs" under "Manage GPU Utilization". With this setting, Lightroom performs as expected and considerably faster. Even the less intensive tasks fly through impressively fast.

The GPU does run hotter (the fan is constantly running faster). Impacts to other applications have yet to be determined definitively but, thus far, it does not seem to cause any issues. Some performance improvements have been observed and even various graphics heavy applications appear to work well, if not better. Some games do seem to struggle at times but this experience is yet to be fully confirmed.

Aside from this change, I will be contacting Adobe and providing this experience to them for analysis and comment.

I think what you observed is the trend that software developers now using the GPU for general computing also rather than just graphic.

Are you using the Game or Studio Nvidia driver?

Off subject, just had a peek at some of your photos.

I am not a windows guy, but you have a pretty powerful machine, for it to completely hang like that seems odd.
You have plenty of RAM & Fast Drives. (scratch disk??) (was the file an extra large one?)
Are there any updates to the App or the OS that might need to be done?
I would check that, then call Adobe support
