Adobe Lightroom Classic (v.10 and newer)

Adobe Lightroom Classic is a robust tool for photographers, offering detailed photo editing and catalog management. Enabling GPU acceleration can significantly improve performance, especially when working with large RAW files or high-resolution displays.

How to Enable GPU for Display and Image Processing in Lightroom Classic

1. Launch Lightroom Classic
   Open from the default path:
   C:\Program Files\Adobe\Adobe Lightroom Classic\Lightroom.exe

2. Enable GPU Acceleration

   • Go to Edit > Preferences > Performance.

   • Set Camera Raw: Use Graphics Processor to Custom.

   • Check both Use GPU for Display and Use GPU for Image Processing to fully utilize the GPU for faster display rendering and image editing tasks.

3. Verify GPU Use
   In the Performance tab, you can view details about the GPU being used. Ensure your GPU is supported for display and image processing acceleration.

Top Tips to Speed Up Adobe Lightroom Classic

1. Increase Camera Raw Cache Size
   Boosting the Camera Raw Cache size to 20-50GB can significantly enhance the speed of preview generation and image processing. You can do this in Preferences > Performance. Storing the cache on an SSD will further improve performance, as it allows Lightroom to quickly access stored image data.

2. Use Smart Previews
   Enabling Smart Previews lets Lightroom work with smaller, more manageable files, improving editing speeds without sacrificing final output quality. You can turn this on in Preferences > Performance to enable faster editing.

3. Optimize Your Catalog
   Regularly optimizing your catalog is crucial for maintaining speed and performance. This process cleans up the catalog’s data structure, helping it run smoother as your photo collection grows. Do this by selecting File > Optimize Catalog.

4. Turn Off Unnecessary Features
   Disabling autowrite XMP (found under Catalog Settings > Metadata) can significantly improve performance. This feature constantly writes metadata changes to sidecar files, slowing down Lightroom during intensive editing sessions.

5. Use a Fast SSD and Ample RAM
   Storing your catalog and images on an SSD greatly reduces loading times and speeds up file access. Additionally, having 16GB or more RAM will help Lightroom handle large files and multitasking more efficiently, especially during imports and exports.

Top Recommended GPUs for Lightroom Classic

1. NVIDIA GeForce RTX 3060 Ti
   This mid-range GPU provides excellent performance for Lightroom’s GPU-accelerated tasks, such as image processing in the Develop module.

2. NVIDIA GeForce RTX 3070
   A great choice for users with high-resolution displays or large catalogs, the RTX 3070 offers strong performance and future-proofing for upcoming GPU features in Lightroom.

3. AMD Radeon RX 6700 XT
   Another solid option, this GPU handles Lightroom’s demands well, offering great value for both image processing and multi-display setups.

By enabling GPU acceleration and following these tips, you’ll ensure a faster, more efficient workflow in Lightroom Classic, making it easier to handle large-scale photo editing and processing tasks.
