Lightroom does not currently utilize the GPU for performance improvements. It is outlined in the Lightroom documentation here. Lightroom requires a video card that can run the monitor at its native resolution. Built-in, default cards that ship with most desktop or laptop systems typically suffice for Lightroom.
One of the next things we wondered was how does Lightroom leverage the graphics processor?
You can use devices with a compatible graphics processor (also called a graphics card, video card, or GPU) in Lightroom to speed up the task of applying edits to images in Detail view.
If you run Lightroom Classic on a Windows computer, using a compatible graphics processor accelerates rendering of images in the Library module’s Grid view, Loupe view, and Filmstrip. Enhance Details feature in Lightroom Classic is also accelerated by GPU.

How do I choose the right CPU for Lightroom?
There are two primary factors to weigh up when selecting a new CPU. The number of cores on the single CPU ( two physical CPU’s don’t help much) and its clock speed. Lightroom makes good use of multiple cores for image processing tasks such as building previews, working in the Develop module, and exporting photos.
As you can see from the graph, the time it took to import our 80 RAW test images into Lightroom did not change at all based on the number of CPU cores available. However, this is the one action we tested where we do not believe the CPU was the main bottleneck. Instead, it appears that even with the fast Kingston USB 3.
Does lightroom use multiple cores?
Lightroom makes good use of multiple cores for image processing tasks such as building previews, working in the Develop module, and exporting photos. It’s worth selecting a quad-core processor if possible, even though some other areas of the program are only lightly threaded.
This begs the query “Is a higher or lower core count better for Lightroom?”
If you find that the only thing you are ever waiting on is exporting images to a disk, then a CPU with a high core count will likely give you the best performance. However, the more time you spend waiting on almost anything else in Lightroom makes a lower core count, high frequency CPU better and better in terms of performance.
Does Lightroom support multi-threading?
In this article, we want to find out how well Lightroom can utilize multiple cores – known as multi-threading – to help determine what type of CPU (either one with a high frequency or a high core count) will give you the best possible performance.
