Lightroom CC Performance Issue (Slow)

Hello everyone,

I just updated to the brand new Lightroom CC (and Classic).
Unfortunately, the performance is really low despite the fact my hardware is brand new.



I have around 32k photos and when I scroll through my library, it takes few seconds before it reacts. In the develop module, it is not really reactive...

I noticed that if the Lightroom window is small, the user interface is much more reactive.
Is my Graphic card the problem? Retina screen?

I just contacted the Adobe Lightroom support but they were not able to solve my problem.
They informed me that this problem might be solved in the next version of Adobe Lightroom.
Let's wait and see... In the meantime, please share if you experience similar issue.

Kind regards,
Servan

Servan, can you clarify whether you see slow scrolling performance in Lightroom CC or Lightroom Classic?  You mention both, but then you talk about the Develop module, which leads me to think it is Lightroom Classic.  

Also, try turning off the GPU in preferences and see if that makes a difference.  If it does, that will be helpful information to have. 

Thanks,
Becky

Hello Becky,
Thank you for your answer.
Actually I am experiencing in both Lightroom CC and Lightroom Classic this problem. But Lightroom CC is slower than Classic. When it is in full screen on my iMac, the scrolling is really not responsive and it takes 1-2 second before it reacts. I tried to deactivate the GPU in preferences but I do not notice any improvement.
We also tried together with the Adobe Chat support without success.

Just an update:
As I was looking for a solution, I noticed that Adobe Lightroom requires an OpenGL compatible graphic card. However, the new macOS High Sierra uses "Metal" as Graphic Acceleration. Could it be that Lightroom is not yet compatible with Metal?

See below the System Info of my iMac from Lightroom CC:

Lightroom and Camera Raw recently moved to support Metal on Mac and D12 on Windows.

Is Lightroom CC still churning on uploading images? That can be a taxing on the performance to some degree. There are some optimizations for scrolling on Mac that are being worked on.

Hello Jeffrey,
Thank you for your feedback. Yes you are right. I am uploading 32k photos currently and it is running since 2 days now. It is also slow even though I have a fast internet connection.
I got your point but I do not see how uploading can impact graphic performance. I am not an it expert but I think user interface is managed by the GPU and uploading pics should barely take any ressource but more internet bandwidth.
