There are various possible causes for PowerPoint's sluggish performance, including:- As was already noted, insufficient RAM might make PowerPoint run slowly, especially when working with lengthy, complex presentations. Outdated hardware: Your computer may not have enough power to run PowerPoint smoothly if its CPU or graphics card is outdated. Multiple apps running simultaneously can slow down your computer and cause PowerPoint to lag. If you have several programs open at once, PowerPoint may lag. Large file size: Your PowerPoint presentation file's size may affect how long it takes to open and run. Corrupted file: A corrupted PowerPoint file can make the software run slowly or even crash. Closing background applications, upgrading the hardware in your computer, and minimizing presentation file size are just a few of the ways you might try to increase PowerPoint's speed.
