Lightroom Classic is a powerful editor, but large photo libraries and RAW files can sometimes make it feel sluggish. The good news is that with a few tweaks, you can dramatically improve performance—even on older machines.
1. Build Smart Previews
Smart Previews are smaller versions of your RAW files. They let you edit faster while keeping edits synced to the full-size file.
- Go to Catalog Settings → File Handling.
- Check Build Smart Previews on import.
2. Optimize Your Catalog
Over time, your catalog can get bloated. Lightroom has a built-in tool to fix this.
- Go to File → Optimize Catalog.
- Do this monthly to keep things running smoothly.
3. Use GPU Acceleration
Lightroom can tap into your graphics card for smoother editing.
- Go to Preferences → Performance.
- Enable Use Graphics Processor.
- Choose Custom and turn on “Use GPU for Image Processing.”
4. Manage Your Previews
- Build Standard Previews for faster Library browsing.
- Delete old or unused previews in Catalog Settings → File Handling.
5. Adjust Cache Settings
- Increase Camera Raw cache size to at least 20–30 GB.
- Store cache on a fast SSD for best performance.
6. Use Fast Storage
- Keep catalogs and previews on your fastest drive (SSD).
- Store original files on an external HDD if needed, but keep active projects local.
7. Keep Lightroom Updated
Adobe regularly improves speed and GPU support. Always update to the latest version.
Final Thoughts
Lightroom Classic doesn’t have to be slow. By optimizing previews, using Smart Previews, and fine-tuning settings, you can cut editing lag and speed up your workflow significantly.
