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: Lightroom Classic version: 7.2 [ 1156743 ] License: Creative Cloud Language setting: en Operating system: Windows 10 Version: 10.0.16299 Application architecture: x64 System architecture: x64 Logical processor count: 8 Processor speed: 3.0 GHz Built-in memory: 65385.5 MB Real memory available to Lightroom: 65385.5 MB Real memory used by Lightroom: 4174.9 MB (6.3%) Virtual memory used by Lightroom: 4716.9 MB GDI objects count: 878 USER objects count: 2907 Process handles count: 2048 Memory cache size: 213.2MB Internal Camera Raw revision: 894 Maximum thread count used by Camera Raw: 5 Camera Raw SIMD optimization: SSE2,AVX,AVX2 Camera Raw virtual memory: 1092MB / 32692MB (3%) Camera Raw real memory: 1094MB / 65385MB (1%) System DPI setting: 96 DPI Desktop composition enabled: Yes Displays: 1) 1920x1080, 2) 1920x1080, 3) 1920x1080 Input types: Multitouch: No, Integrated touch: No, Integrated pen: No, External touch: No, External pen: No, Keyboard: No Graphics Processor Info: DirectX: NVIDIA Quadro P5000 (22.21.13.8266) 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. Thanks...
