What Is and Isn’t GPU-Accelerated in Lightroom? GPU acceleration in Lightroom is only available within the Develop module, so no other modules, including the Library module, will be accelerated. On top of that, not all the tools within the Develop module benefit from GPU acceleration either. So if you are wondering what specific tools are accelerated, below is the full list: Panels: Basic Tone Curve HSL / Color / B&W Split Toning Detail Lens Corrections Transform Effects Camera Calibration Tools: Crop & Straighten Graduated Filter Radial Filter Actions: Panning and Zooming And here is the list of specific tools and actions that are NOT GPU-accelerated: Spot Removal Red Eye Correction Adjustment Brush Using Brushes with Gradient and Radial Filters Loading RAW Images Generating JPEG Previews HDR Preview / Generation Panorama Preview / Generation Facial Recognition Please note that the above list is compiled based on Lightroom CC 7.1. Prior versions of Lightroom did not have panels such as the Detail panel GPU-accelerated. на форуме адоб указано относительно 6-го лайтрума: 1. GPU support is currently available in Develop only. 2. Most (but not all) Develop controls benefit from GPU acceleration. 3. Using the GPU involves some overhead (there's no free lunch). This may make some operations take longer, such as image-to-image switching or zooming to 1:1. Newer GPUs and computer systems minimize this overhead. 4. The GPU performance improvement in Develop is more noticeable on higher-resolution displays such as 4K. The bigger the display, the bigger the win. 5. Prefer newer GPUs (faster models within the last 3 years). Lightroom may technically work on older GPUs (4 to 5 years old) but likely will not benefit much. At least 1 GB of GPU memory. 2 GB is better. 6. We're currently investigating using GPUs and other technologies to improve performance in Develop and other areas of the app going forward. Правда, это статья от 2015 г., но за прошедшие годы, насколько я знаю, ничего принципиально не изменилось.
