Even though League of Legends isn’t the most resource-intensive game on the market by any means, if your processor or graphics card is outdated, or if your system is simply old in general, you may have low frame rates when playing the game. But, don’t worry as you can boost your LOL FPS.
Another possibility is that your system is capable of running League of Legends, but you’re still experiencing a low framerate while playing the game.
If you’re having trouble with your frame rate in League of Legends because of a hardware or software issue, you’ve come to the right place as we’ve put together a list of ways in which you can boost your FPS and overall performance. Follow along, as we will first see the causes of LOL lag.
What causes League Of Legends lag?
LOL lag occurs when there is a difference between the actions of players and the responsiveness of the game server in response to those actions.
Because the game server would not react instantly in this situation, even if you had taken the initial shot first, it is possible that your opponent would be able to take the initial shot and win the game.
Ping spikes are a common cause of lagging in League Of Legends. Ping is a measure of latency or the time it takes for a signal to travel from its source to your computer and back. When it comes to gaming, a low ping is beneficial because it implies less lagging.

Because ping is concerned with how quickly a device can acquire data from another server and return it, the less time it takes, the lower the ping and the faster the game may be played is.
The most noticeable effect of a poor internet connection in cloud-based games is increased ping. It is also affected by the volume of data that a network is juggling as well as the number of people connected to that network.
It is also possible that the problem is related to the game setup. When your PC’s settings are not optimized or its hardware requirements are insufficient, issues such as low frame rates are common.
Another factor to consider is the overall performance of your machine. You may do this by looking at your system’s Task Manager, which will provide you with the information needed.
How can I boost my League Of Legends FPS?

Instead of manually updating your drivers every time you face an error related to them, you can opt for a third-part software that automatically updates, replaces, and fixes your device drivers.
Some of the most common Windows errors and bugs are a result of old or incompatible drivers. The lack of an up-to-date system can lead to lag, system errors or even BSoDs.To avoid these types of problems, you can use an automatic tool that will find, download, and install the right driver version on your Windows PC in just a couple of clicks, and we strongly recommend DriverFix. Here’s how to do it:
- Download and install DriverFix.
- Launch the application.
- Wait for DriverFix to detect all your faulty drivers.
- The software will now show you all the drivers that have issues, and you just need to select the ones you’d liked fixed.
- Wait for DriverFix to download and install the newest drivers.
- Restart your PC for the changes to take effect.

4. Change in-game settings
If you’re playing on old hardware, lowering the graphical settings in the game’s graphics menu can provide a big increase in frame rate.
For anyone experiencing unacceptably low frames rates in League (for example, less than 20 frames per second), the best course of action is to just set everything to Very Low (and disable Anti-Aliasing and Wait for Vertical Sync) and hope for the best.
In case you’re experiencing really low framerates, you may want to consider lowering the game’s resolution, as your system’s GPU will have an easier time churning out lower resolution frames.
There are also a few small HUD options that, when turned off, can provide a frame rate increase to the player. You may find out more about them by selecting the INTERFACE option from the game’s settings.
If you uncheck Enable HUD animations, Show Target Frame On Attack, Enable Line Missile Display, and Show Attack Range, you may see a significant improvement in performance, making the tweaks to your HUD worthwhile.
5. Clean temp files
- Open the Windows search function and type %temp% inside it.
- Once you have entered the Temp folder, select all the files and delete them. Skip any files that won’t be able to delete.
It’s possible that your hard drive is clogged with unnecessary files. If these files are not correctly deleted, they will cause slowness.
