Hi, I'm using Lightroom classic on a 15 month old iMac Pro, which is usually lightening fast, with a powerful graphics processor and lots of RAM. I'm still running Mojave as I have a number of programs incompatible with Catalina.

After updating to 9.2.1 I'm finding that the adjustment brush in particular is running really badly, with beachballing happening after only a few strokes with the adjustment brush. It always used to work instantly. The same with noise reduction, I used to have instant results as I moved the slider but now its move and wait.

I've run diagnostics on my machine and all comes back as working properly.

I've tried purging the cache which made no difference.

Please help as its becoming unusable. I can't really work with lightroom like this.

Can you try setting the GPU to off (Preferences > Performance) and see if that affects it?

I would be surprised if it was 9.2.1 causing, but you could roll back to 9.2 to test (see blog)

Try turning off sharpening and noise reduction for the initial edit of your image. When finished all other edits then adjust noise/sharpening to taste. This should reduce the amount of detail processing required to apply individual brush edits. If you have a lot of brush style edits try to do them in Photoshop.
