    Hello,

    because the performance of lr was slowing down with Lr 9.x, I decided to bite into the sour apple and replaced my 2014 Macbook pro with the latest model ( 32GB ram, Core-I9 w/ 8 cores, 5500 pro gpu w/8GB).

    In the development module, Lr is pretty fast, also when using many local adjustments with the paintbrush or any other tools, but when simply watching my images, especially when in the full screen ‘F’ mode, it is pretty slow to go from one image to the next one with the arrow keys.

    GPU acceleration is switched on manually, so all options are switched on, and the cache is set to 50 GB.

    Since my camera is an Olympus E-M1 mark II / mark III, the size of my image files is just 20MPx, so in my opinion Lr should fly on this hardware.

    Does anyone else experience the same issues, or have any idea what screw to turn to make Lr run as expected ?

    Many thanks future answers or hints ! Robert

    Best regards Robert

    It’s always good to start here when addressing LR performance issues:

    While I admittedly don’t have any links to back this up, I also recall seeing multiple references to LR’s UI performance not scaling well with higher and higher monitor resolutions.  Note that Retina screens have 4 times the pixels of equivalent non-retina resolutions.  And anecdotally, resizing LR’s window to 1/4 of my retina screen dramatically improves its responsiveness in moving through the library module.  Too bad I don’t want to use it this way!

    So if you happen to have a non-retina external monitor, it might be worth seeing if LR speeds up significantly during fullscreen image viewing on it.

    Either way, judging from how responsive a fullscreen Apple Photos is (or even the Finder, browsing a large folder of images), I think Adobe is still seriously dropping the ball with Lightroom Classic’s UI performance.

    Thanks, I opened a thread at Adobe !

    Hello,

    since the update 9.3  provided by Adobe today to my MBP, the problem is solved now.

    The performance is at least at the point where it was with version 8, but I think it is faster.

     

    BR Robert
