7. Improve Lightroom’s Performance
If Lightroom is running slowly, I’ve got three things to check to improve its performance:
- On the Lightroom Preferences > Performance tab, toggle the Use Graphics Processor off if you use integrated graphics or older GPUs. Many users report slower performance with this setting on, surprisingly.
- On the Preferences > File Handling tab, greatly increase the size of your Camera Raw Cache. I leave mine set to 30 gigabytes.
- Periodically, run File > Optimize Catalog as a housekeeping step.
