Lightroom Classic v9.1 - Lag issues with Adjustment Brush

Hello everyone!

 

I am currently having major lag issues between photos I am editing. It has come to my attention that it's a lag issue with the Adjustment Brush. I've used the Adjustment Brush to make sure my photos have a perfect 255 background. However it seems I cant even use the Adjustment Brush at the moment. The lag can be anywhere between 2-3 minutes long switching from one photo to the next. Does anyone else have this issue? Has anyone found a round about or a fix to it? It would help majorly since this is something I use for work.

 

Also I have disable GPU and I have bumped up my Cache. And yes I even Purged Cache before coming to the community board 🙂

Lagging adjustment brush with a 5K monitor is a common problem. I'm not aware of a good solution — turning of the GPU acceleration ought to help, but it may cause other areas of slowness. You can also try a smaller monitor (smaller in pixels, not smaller in inches), or try working with smart previews rather than the actual original image.
