LoL FPS Drop: Causes & 8 Ways to Fix It

One of the most common issues players face in League of Legends is random FPS drops. Some experience these drops when moving the camera, the mouse, or even at random moments during gameplay.

These drops might be due to a LoL FPS bug, with some players reporting the issue after installing Vanguard. High ping can also be at fault. Regardless of the cause, here’s how to fix it:

How can I fix LoL FPS drops on PC?

Before we start,  make sure your computer isn’t overheating , try disabling all game sounds, and undo any recent overclocking.

1. Close unused apps

1. 1. Press Ctrl + Shift + Esc to launch the Task Manager.

2. 2. In the Processes tab, you’ll see all the programs currently running on your computer.

3. 3. Click on the CPU column to sort the active processes.

   

4. 4. Select the processes that take up much CPU and right-click on them.

5. 5. Click on End task.

   

A great way to fix FPS drops in LoL is to close the apps you don’t currently use. It is likely that your CPU is being used by them and that is why you are experiencing lag in your game.

Ending the unused apps can be easily done via Task Manager. All you need to do is sort the list of tasks by CPU usage and end those which use up a lot of it, for which you have no important use at the moment.

2. Optimize game settings

Adjusting game settings can help find a good balance that stops sudden FPS drops in LoL.

Video settings

1. Open League of Legends and enter a game.
2. Press Esc Key to open Options.

3. Click Repair and wait for the process to finish.

The repair process can take up to 30 minutes, depending on how bad the situation is, so be patient. This will ensure LoL works fine, preventing FPS drops and PC crashes.

7. Reset your graphics card software

Graphics cards come with their own software: NVIDIA comes with the NVIDIA Control Panel and AMD has the Catalyst Control Center.

Reset the NVIDIA Control Panel:

1. Right-click on your desktop and then select NVIDIA Control Panel.
2. Select Manage 3D Settings.

2. Select Catalyst Control Center/ Vision Center.
3. Go to Preferences.

2. Select High Performance from the list of power plans.
3. Save settings and go bag to League of Legends.
