Lightroom Classic CC 7.2 still slow with high resolution

After reading the so-called solutions the performance of Lightroom Classic is HORRIBLE! Thumbnail images do not update as more images (eventually) are imported into Lightroom. Importing takes far too long to be productive. I just admit I am surprised. This experience reminds me of when Apple started screwing up their applications. I guess Adobe is now following along the same path. If it continues, I will look elsewhere for an application with speed a performance. Maybe On1 or perhaps EyeCandy's Exposure. This ain't going to work. I shoot thousands of photos a night doing concert photography. Adobe FIX THIS!

The latest release of Lightroom Classic CC release 7.2 is much slower for me as well. and I'm running a brand new Dell Mobile Workstation Precision 7720 (purchased one month ago) with 64 GB RAM and a 16GB NVIDIA P5000 graphics card, and "Use Graphics Processor" activated.

1. Opening a photo from Lightroom to Photoshop for editing (right-click > edit in Photoshop) takes 2 minutes or more to open in PS. Before upgrading to release 7.2, this was almost instaneous.

2. Once I finish editing the photo in Photoshop, and save it back to Lightroom, the edited image never appears in the folder in Library module. So I try clicking off the folder, and then back onto the folder again, and I get a message that says "loading", but it never reloads the images in the folder, or any other folder for that matter. Eventually I have to shut down Lightroom and restart it to get the folder to load, and voila, the edited image is now in the folder.

All of this was taking too much time, so I had to downgrade back to Lightroom Classic CC release 7.1. The following is my system info before downgrading:

SanderTaats  wrote Are there any plans on making Lightroom work fast with higher resolution screens as well? I run it on a lower res monitor just for the speed but on my 4k display at full screen the software is painfully slow. When I make LR window smaller on the same monitor then it speeds up again. I have 2 fast m.2 hard drives (C: and D:) and decent computer so it should be able to handle it in full screen.

Slow at what? Be specific. The announcement about LR 7.2 doesn't say anything about speeding up the Develop Module, it says:

Experience faster Lightroom Classic performance on machines with 12 GB of RAM or more, when you import and export photos, move between photos in Loupe view, or create HDR images and panoramas.

Do you have activate the GPU support?
