Lightroom Classic Painfully Slow

It appears I’m not the only one experiencing extreme slowness with Lightroom Classic.  Since upgrading, LR has become painfully slow in import and export.  I’ve also noticed that when in the Develop module, there is a delay in response on the image when using the various sliders in all groups.

I’m also getting a message stating that LR is causing a high CPU usage. I’m running LR on a Windows 10 pro machine with an Intel i7-6700K 4ghz processor, 2 M2 SSD drives, one as a scratch drive and 32 gb memory.

I’ve never had such a slow response on earlier versions of LR CC or stand alone.  What’s up?

    i have the same problem with LR 8 classic. it's horrible.

    i noticed that this thing never even uses more than 30% of the CPU and less than 50% of the memory.

    i changed the computer, added more RAM, bought nvme drives, and this thing still works the same. it doesn't take any advantage of the hardware. LR 8 is so awful that i can't even drag and drop images when it gets slow. LR is reaching a point that start to be impossible to use for work.

    Hello, I'm a MAC user and I decided to deactivate the use of the gpu processor and use smart previews and now it is faster, specially when using filters, brush mask and cropping, before I did this my lightroom was painfully slow, every time I tried to develop a picture and work with filters and brushes it would get stuck and have to wait for several minutes for it to react, now is better, is not perfect but it is way better.

    LR Classic is frustratingly slow. It is taking longer and longer every day to do simple tasks like culling images or small adjustments.

    In this industry, time is money. I can't charge my clients more, because my tools take so long to do their job.

    We shoot raw, because it allows us to improve our quality. But his is costing us in time. I'm now shooting in JPG again because somehow Canon can adjust the raw file with sharpness, saturation, etc and export to jpg in a fraction of a second on a ARM based low power CPU while Adobe can't even render a single adjustment in less than a second on a high end PC.

    Seriously considering other alternatives at the moment.

    As an initial troubleshooting step, uncheck the option Preferences > Performance > Use Graphics Processor.

    Hi John,

    I have a Nvidea GTX 970 video card with 4gb VRAM.  Lightning fast with LR and PS CC up until the upgrade to LR Classic. Everything I've read says using the graphics processor should speed things up, especially with that card. I'll give it a try but it sure doesn't make sense that the GPU should slow down LR.

    Thanks.

    Adobe is changing the GPU support code in every release. It may not be the GPU causing your issues, but historically it is a frequent culprit.
