How To Increase FPS While Playing League Of Legends


On the web, you can find several configuration files to replace yours and boost the fps. In this article we will discuss about how to increase FPS while playing league of Legends.

These adjustments are useful if you are struggling to reach an acceptable amount of fps as you are using a low-spec PC, but also if you have a monitor with a high refresh-rate as you bought it to gain an edge in a competitive game such as League of Legends.

How To Increase FPS: Client options

First of all, we must optimize a few settings inside the game client. Depending on your machine, you might gain even 10-20 extra FPS.

Launch the League of Legends client, and click the Options icon at the top right.


  • Enable Low Spec Mode: on.

Enabling this setting reduces visual fidelity in certain areas of the client, but it may improve performance.

  • Close client during the game: on.

Enabling this setting will close the client to improve in-game FPS on old and low-spec machines. However, note that it will also increase the amount of time it takes to return to the scoreboard at the end of a match.

Interface How To Increase FPS

  • Enable HUD Animations: off.

HUD Animations have been polished over time, so they do not reduce fps significantly anymore, but it is still worth to disable them if you need as many frames as possible.

In-game settings

While inside the game client, click Play at the top left, and join a game. You can also create a custom lobby to test the settings.

When in-game, press the Esc key on the keyboard to open the Options and then select the Video tab. I will show you how to set up each set for maximum performance.


  • Resolution: use your native one.

Using your native resolution is desirable for a better view, but if you badly need a performance boost, decreasing the resolution will greatly improve your fps. 720p is usually a solid compromise between quality and performance.

  • Windowed Mode: Full Screen or Borderless.

Full Screen is the best choice performance-wise, but you might prefer Borderless if you have a multi-monitor setup and you wish to move quickly on another display.

Note: you can switch from Full Screen to Borderless by pressing Alt+Enter on the keyboard.

  • Hide eye candy: on.

It disables some ambient effects. It has only a minor impact on performance, but it helps to avoid unnecessary visual distractions.

  • Enable screen shake: off.

I warmly recommend disabling this setting because it generates visual effects on your screen that can influence negatively your gameplay.


  • Graphics: Custom.

This slider is the simplest solution to tone down the graphic if you don’t know what are you doing, but I prefer selecting individually each option.

Here are some comparative images with the slider set to Very Low and Very High.

  • Character Quality: Low.

  • Environmental Quality: Low.

  • Effects Quality: Low.

Overall, Low is a solid compromise between graphic quality and performance.

If your PC really needs the extra FPS, you may be forced to use Very Low, but be aware that there is a considerable loss in visual quality: the game will look extremely bad.

How To Increase FPS

  • Shadows: Off or Low.

In my opinion, Shadows drastically improve the visual look of League of Legends, but they have a huge impact on the performance.

  • Character Inking: off.


  • Frame Rate Cap: your monitor refresh rate.

This is the fps cap. I suggest keeping it at the same value as your monitor refresh rate (60, 120, or 144Hz).

Note that unlocking the frame rate might cause overheating problems if your system isn’t cooled properly as the game will try to render as many frames as possible.

  • Anti-Aliasing: off.

Turning off Anti-Aliasing is the best option if you want to improve your FPS.

  • Wait for Vertical Sync: off.

Game.cfg file

To find your game.cfg file, press Win+R and then input the following line:

D:\Riot Games\League of Legends\Config

Replace “D” with your Hard Drive letter.

How To Increase FPS, Right-click on game.cfg and open it with WordPad or another text editor. I use Notepad++.

There are several options, but all the ones related to graphics and performance have been already set up via the in-game settings.

Editing the game.cfg file can be useful if you experience rare issues such as the necessity to increase the cursor scale when playing on a 4K monitor.

Note: If you edit the file, don’t forget to mark it as Read-Only.

How To Increase FPS Right-click on the file, go on Properties, General, Attributes, and mark it as Read-Only. If you don’t, it will be overwritten as soon as you start the game, and you will lose all the changes.

If you need to alter your in-game settings in the future, it is necessary to uncheck read-only. Afterward, you can change the settings, edit manually the game.cfg file, and set it as read-only again.

How To Increase FPS: Make Changes Outside the Game

If you’ve tried altering in-game video settings and updating your drivers, it may be time to consider making alterations to Windows or League itself. This is a big move, so if you aren’t familiar with making adjustments like this, take care to ensure that you don’t do any permanent damage to your system.

How To Increase FPS, The simplest thing you can do outside of the game to give yourself an FPS boost is to use the Task Manager to set the CPU priority of League. In the “processes” tab of Task Manager, you can right-click on League’s .exe and set the game’s priority to high or real-time. This should give you an immediate FPS boost, as devoting more of the CPU’s power to one program generally makes it run more smoothly.

How To Increase FPS

You can also adjust the configuration file—located in League’s installation folder—to change video settings that aren’t present in-game. For example, you can change “EnableGrassSwaying” from 1 to 0, set Inking to 0, and set PerPixelPointLighting to 0. These changes can have a huge impact on your frame rate, but there are too many options to adjust in the configuration file to dig into each one, so peruse it and make changes at your own peril.

Less commonly, League’s game files may have become corrupted since you first installed the game. Fortunately, this is an easy fix: Once you run the game launcher, click on the settings cog in the top-right corner of the window and select “Initiate Full Repair.” This could take five minutes, or it could take half an hour—it all depends on how many files are corrupt and how powerful your system is.

Another very simple fix is to ensure that no extraneous programs are running when you’re trying to play League—especially anything that’s resource-intensive. One of the biggest culprits of resource-hogging are browsers, which can occasionally experience memory leaks, hogging up to half a gig of memory at a time. Make sure you aren’t running any programs that you don’t need when you’re trying to play.


Ultimately, to How To Increase FPS, you have quite a few different options to use in order to How To Increase FPS problems in League of Legends. My guess is that, since League of Legends is not a very demanding game, one of the first three options will solve your problem. However, if you’re currently playing on an older system that didn’t have great hardware to begin with, you may need to look into options four and five. Fortunately, getting a new GPU—or a new system entirely.
