CPU overworking with Lightroom Classic CC update to 7.3

  • April 4, 2018

Hello, has anyone else noticed that whenever you open Lightroom Classic CC after the 7.3 update that CPU activity jumps? My MacBook Pro's fans have been going hell for leather everytime I open Lightroom Classic CC. I've not read about this problem anywhere else yet so just wanted to mention it to see if anyone else has noticed it.

I'm using an MBP Retina 13 inch early 2015 with 16 GB RAM and 3.1 GHz Intel Core i7 processor.

Thanks

I unchecked the GPU in preferences, closed down Lr and waited for my system

to settled and then restarted Lr. Soon after the restart, Lr starts taking

up the %CPU in activity monitor. It sits at >350.

Something associated with Lr is running in background. Unfortunately, find what that might be can be tricky.

Five items spring immediately to mind:

1. One time hash for LR CC sync: While I don't believe it's relevant to Lr7.3 please check out this article Issues after updating to Lightroom Classic CC 7.2

2. Lightroom syncing files to Creative Cloud: Check Lr Preferences>Lightroom Sync panel. Unless you are syncing files there should be no activity

3. Face tagging is On: Check status of Face Detection in Catalog Settings>Metadata panel. If you don't use face tagging then it should be unchecked.

4. Embedded Previews: Lr Preferences> General panel. Check status of 'Replace embedded previews... during idle time'. If you don't use embedded previews during import this preference should can be unchecked.

5. Auto write changes into XMP: Check status in Catalog Settings> Metadata panel. Ideally, the preference should be unchecked.

I had a similar problem, with the CPU sitting at about 125% all the time, LR being idle (no preview building etc., sync off). Taking into account what Ian wrote earlier, I switched on sync and deactivated all plugins I dont really need. Restarted LR and voila, I´m down to about 2%. I thought, hey, it´s the darned 3rd party plugins (Koken, Palette) that caused this. So I stopped the sync, began to write this post, checked again and we´re back at 130%. I´m confused now. Isn´t it meant to be the other way around?

/e: Oh, I´m on an early 2015 Retina MacBook pro with OS X 10.13.5 and LR 7.4.

    I have checked all of the alternatives multiple times... LR is still running sluggish and kicking the CPU hard,   up to 5-600%. Any other advise?

    Yup,

    I have exactly the same issue. Lightroom is gobbling up CPU like there's no tomorrow. Unchecking the GPU makes no difference:

    While I'm glad it's not just me, it sucks that others are affected too. I

    hope this doesn't turn out like the auto import saga.

    Hi GaryLum,

    Thanks for the feedback. Could you please share your system info with us? Go to Lightroom Classic > help menu > system info and provide the dialogue information or you can post a screenshot of the same.

    Also, have you tried unchecking the GPU from the Lightroom preferences and let us know if that helps.

    Regards,

    Mohit
