Lightroom Classic: Very slow rendering in Develop module

hi folks,just installed LR CC. Rendering in develop module is really slow. Eg. when I move between photos, it takes a good 3 seconds for the photo to fully render. Displays "loading" for about 2 seconds and then a further second or two before the image is fully rendered.This isn't happening in the Loupe view.This is with a new set of photos I just imported, and I had "build 1:1 previews" set during import.Is this an issue or have I got a setting wrong somewhere?It wasn't quite this bad on LR 5.ThanksDave

    I've the same issue.  It's horribly slow, and isn't an issue with my computer everything else runs just fine.

    Same here, although it seems to be a recent update because it never used to be this slow! I have Win 10 64-bit,  32GB RAM, Quadro K4200 graphics and Intel Xeon, 8 core 3.4Ghz which flies through everything else.

    I basically have to restart LR every hour or so otherwise its just unusable. If they can't get this fixed I may hve to give up my CC accounts 😞

    Mu Lightroom runs faster after upgrading to a 6th Gen core i7, 32Gb RAM, 2 x SSD's, GeForce GTX950. But... 

    I have to disable the GPU to get the brushes smooth. After working for an hour or so, I have to restart Lightroom, because it becomes so slow. I've tried everything. Separate SSD's for Cache and LR Catalogs, latest GPU drivers. Freshly installed OS. Newly installed LR 2015.6... To no avail. 

    After building HDR-Panoramas in LR, I get the error message, "File Appears to be damaged", even though I can edit and export it perfectly. These are all issues we have to contend with. 

    I love everything about Lightroom, except the speed and bugs. Lightroom isn't a mature product for professional photographers, and I can see why a lot of photographers stick to a Bridge and ACR workflow.

    I'm a carbon copy of most other posters here.  Running CC 2015.6, Win 10,  3.6 GHz 8 core i7, SSD, 32Gb, GeForce GTX770 with latest drivers. This is a fast machine that just eats PremierePro  projects and absolutely anything I throw at in in PS.  It has been cracking fast in LR but has slowed down to the point I feel like screaming while churning through 200-400 file projects. The only thing that's elevated is my blood pressure.  If I use ACR it's red hot, weird ...

    I've done the usual stuff, clear cache,  trash preferences, toggle GPU, disabled plugins, done proper FULL Win10 shutdown. I'm at my wits end. It wouldn't be that big a deal to uninstall LR and reinstall. Is this known to help? And yes, I'm using a Wacom PTZ-630 tablet.

    I fixed the "LR is ridiculously slow" problem by disabling all plugins in File --> Plugin Manager. I was having the same problem waiting up to 10 seconds for previews to display on a super super powerful desktop.

    Hi Simon, It may help if we had your system info. Can you launch Lightroom and select Help > System Info... and copy paste the contents of that dialog in a reply?

    I'm having the same issues. LR just cannot handle large files in develop without bogging down completely. Turning off the GPU has no effect either. I have 32GB of RAM and a good graphics card so this should not be an issue. Very frustrating. LR was better in previous versions.

    I've had it with slow Lightroom CC and all the other issues like error reporting like "The image Appears to be Damaged". My PC might not be brand new, but with a Core I-7 CPU and 12 GB of Ram, the lag time is getting to me.

    Turning this off SIGNIFICANTLY improved the performance of moving between photos in develop mode. Thank you!
