Lightroom creates preview images of your projects, and these can slow down the program. If you are lacking in the hardware department, consider upgrading your computer, or certain aspects of it. Reduce your screen resolution if you need to. If you have a monitor with a high pixel count, this will also be a draw on the software, as it needs to update each pixel when you make a change. Adobe keeps a list of recommended GPUs for Lightroom. But having a dedicated card with at least 1 GB of VRAM will greatly increase your performance. Even if you don’t have a dedicated graphics card, and only have an integrated one, your computer should be able to run Lightroom. Having a good graphics card will be useful as well. If there isn’t enough free space, it can perform slowly, so try to keep at least 20%-25% free space on the drive you store Lightroom and its project files on. Also make sure that your hard drive has enough free space. If you must use an external hard drive, make sure that you use a Thunderbolt or USB-3 connection for fastest speeds. Obviously having a solid state drive will speed things up. For file storage, a typical SATA hard drive will be sufficient. Higher RAM will speed up importing and exporting, as well as your workflow with panoramas or HDR images. Adobe recommends that your computer has at least 12 GB of RAM. If you work with larger, more complex files, then you will need more powerful hardware. Double-check that your machine is powerful enough to run Lightroom. Sometimes it’s not the software, but the hardware.
