How to fix low fps

Try updating your graphics drivers, lowering resolution, disabling V-Sync, and turning off shadows and anti-aliasing. Close background apps, set your PC to “High Performance” mode, and check for overheating. If you’re on a laptop, keep it plugged in. If that doesn’t help, consider upgrading hardware or reinstalling the game.
