Since last update my LRC is very slow

[AntonioAcunaR]

Despite having a Ryzen 9 3900x, 64gb of memory and my photos in a fast hard drive (and catalog on an SSD) and with 67% free memory after launching LRC, since last update LRC seems to struggle even to draw the interface, as if it was running out of memory.  I've got no plug ins loading up just LRC.

Has anyone else notied a similar issue with latest version? PS and others like Luminar do not have this issue.

The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the second link.

Another step is to try to reset the Lightroom preferences.

If this doesn't help we need more informations about your environment.

Which operating system do you use?

Which version of Lightroom do you use?

Please post the exact version and not only phrases as "recent", "latest" and so on.

Thanks so much for the advise, done, including updating driver (Nvidia Gforce experience seems slow at picking them up) and it has helped.  Still, compared to other applications, Lightroom is slow, but will have to do until I move to ON1 or Capture One (or maybe even stay with Luminar 4 only).  I have used LR since it started, and it has become slower and slower with each new version.

I've got the same problem on a 2020 iMaC 27 with 80 GB of memory. Excrutiatingly slow.
