When configured (Preferences > Performance), Lightroom Classic can use a compatible graphics processor (also called a graphics card, video card, or GPU) to speed up tasks of displaying and adjusting images in the Develop module, the Library module's Grid view, Loupe view, and Filmstrip. Enhance Details is also accelerated by the GPU. Using a compatible GPU can provide significant speed improvements on high-resolution displays, such as 4K and 5K monitors.
Your graphics processor must meet the minimum system requirements (see below) to be used by Lightroom Classic. We also recommend choosing a graphics card with a GPU Compute benchmark score of 2000 or greater.
2GB GPU RAM
4GB GPU RAM or more for 4k displays and greater
For additional details, see System requirements | Lightroom Classic.
For best performance, use a discrete graphics card that has the GPU Compute benchmark score of 2000 or greater.
When Lightroom Classic is able to use the GPU, you'll find that the Use Graphics Processor check box is selected in Preferences.
In preferences, the name of the GPU available to Lightroom Classic and its available video memory is displayed. If no information is displayed, then you may need to install a new driver for your GPU, or your hardware or operating system does not meet the minimum system requirements.
Introduced in Lightrooom Classic 8.4 (August 2019 release)
In Lightroom Classic, the current status of GPU acceleration is displayed just below the GPU name. Your system may automatically support basic or full acceleration. If your system automatically supports basic acceleration, you can enable full acceleration using the Custom option.
Acceleration may also be turned off automatically if your system does not support it or due to an error. If acceleration is turned off and an error message appears, it could be due to GPU hardware, driver version, or operating system not meeting the system requirements.
You can select one of the following options from the Use Graphics Processor drop-down to turn the GPU acceleration on/off.
Select this option to automatically determine the correct level of GPU support based on your system's hardware and operating system configuration. This is the default option.
Select this option to choose the level of GPU support manually.
Select this option to turn off the GPU acceleration.
To determine your graphics card make and model, launch Lightroom Classic and choose Help > System Info to view the information for your graphics processor.
Lightroom Classic currently doesn't take advantage of more than one graphics processor. Using two graphics cards does not enhance Lightroom Classic's performance.
Multiple graphics cards with conflicting drivers can cause problems with graphics processor accelerated features in Lightroom Classic.
For best results, connect two (or more) monitors into one graphics card.
If you have to use more than one graphics card, make sure that they are the same make and model. Otherwise, crashes and other conflicts can occur in Lightroom Classic. To resolve issue arising because of conflicting graphics drivers, follow Step 5 and Step 6 in Solution 4: GPU and graphics driver troubleshooting steps.
