Lightroom CC Classic Very slow after update

  • Updated 2 months ago
Since the last update, in both Library and Develop, about every 20 seconds Lightroom goes into a Not Responding state.  This lasts for several seconds before working again, but it is very very slow when it works in both modules.  For instance, when reviewing images to Pick or Reject, it takes between 5 and 8 seconds from an X (reject), right arrow to the next image, before it becomes active.  it's really painful.  Can anyone help?  Ive disabled my Graphics Processor, ive increased cache but to no avail.

Annette, that is not typical behavior. Please go to Help>System Info... and copy your exact installed Lightroom version number and paste it here. 

It would also help us to know if you are Windows or Mac and what your OS version is.

Thank you.

Here is my version, which I believe is the current one.

Lightroom Classic version: 7.3.1 [ 1167660 ]


My OS is Windows 10 Home.

It's been running OK until the last update and now in both Library and Develop I get Not responding and then a several second wait - and then it clears for a minute or so - then the same again.

Annette,

7.4 was released today. Try updating Lightroom Classic CC and let us know if it is still misbehaving afterwards.

I ran the update earlier and have only been using it about 10 minutes - but this now looks like it has solved the problem I was having. It's much quicker.  I'll be on it longer tomorrow to give it a full run out.

I've been using it now since the update and whilst it's a bit better, I'm still getting the Not Responding status in both Library and Develop.    I'm wondering as the product evolves, could it be my 8Gb RAM isn't quite enough?

I don’t think so, or maybe but things are quite laggy - spinning circles, a lot of waiting to do things. Import and launching LR is slow and laggy while loading and getting things ready. Photo previews not rendering in thumbnails(grey squares), you name it. I’m on 32GB, Windows 10 and catalogue running off internal SSD

Not my PC then!  That does sound just like the issues I'm having.  It's painful Picking and rejecting images and I've had a load of shoots lately so lots to go through. It's very frustrating.

No I've got into things, its painfully slow and still getting the Not Responding.  It's at a point where I don't want to use it at all.  Please can anyone help?

Annette, generally, the behavior you describe is not normal. Even though your system is slightly underpowered it should still function. I normally prescribe a reinstall - but in a precise way. 

1. Restart your system.
2. Uninstall Lightroom via the Creative Cloud App.
3. Restart your system a second time.
4. Wait 5-10 minutes without launching any other programs.
5. Reinstall Lightroom via the Creative Cloud App.
6. Restart your system. Launch Lightroom and wait 5 minutes after launch for all the processes to catch up.

Is your not responding message still coming up?
