Lightroom Classic CC 7.2 still slow with high resolution

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.

    It is more demanding to show larger files but the difference in speed is too large between working with a 8 MP image (4k monitor) vs a 2 MP image on a smaller display. The original raw file is the same 50 MP.

    None of this is surprising. The larger the image size and the larger the screen size (in pixels) means that the computer has to work harder (it takes longer) to generate the image. In the past, people could claim that the problem was that Lightroom code was poorly written, but the new release of Lightroom takes most of that reason away, and the other possible cause of slowness is hardware that can't keep up. Your 8 Megapixel display and 50 MP images certainly will take huge amounts of processing power to produce reasonable speed as judged by the user, and the evidence indicates that your computer doesn't have that much power.

    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:

    If anyone has any revelations as to how to improve performance with release 7.2 of Lightroom Classic CC, I'd love to hear it. Otherwise, I'll stick with release 7.1.

    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.

    Don't get me wrong, this latest version is a lot faster at the things mentioned but it's still slow. I ran some more tests and the software gets faster at everyting when you make the lightroom window smaller but if it's too small then you can't see what you are working with. It is more demanding to show larger files but the difference in speed is too large between working with a 8 MP image (4k monitor) vs a 2 MP image on a smaller display. The original raw file is the same 50 MP.

    For this test I used only moving between photos in library view but the experience when working in develop mode is the same, it speeds up when the image is shown in a smaller window.

    I tried viewing large resolution images with the default photo viewer in Windows 10 and it didn't matter if I was viewing them in full 4k screen or in a small window. It was equally fast with all sizes. It feels like if only that algorithm was rewritten then the whole software would feel faster in all resolutions.

    Yes, it's activated and camera raw cache size is 25 GB. Also using smart previews.
