Constant updates and years of gameplay can overburden your Client and PC with unnecessary data. Clearing it out helps performance immensely.

As League of Legends updates every two weeks, and keeps records of all games played for every patch, it’s a given that your memory space gets cluttered, even when some are supposed to be just temporary files. Here is how to clear Client Cache League of Legends has when overburdened with log files.

How To Clear League of Legends Client Cache

With or without a bug that makes your cache files balloon to a large size taking up valuable disk space, it’s a given that they will do so on their own if enough time passes. Clearing your Client Cache is an easy way to boost the performance of your game.

Client Cache
  1. Right-click on League of Legends and select “Open File Location”
  2. Open Logs
  3. Open LeagueClient Logs Folder
  4. Select Delete to delete All Log files
  5. Open AppData
  6. Open Riot Games
  7. Open Riot Client
  8. Open Logs Folder
  9. Open Riot Client Logs Folder
  10. Delete every Log folder

As you can see, the Riot Client Cache can be found in two places, and both of those balloon to incredible sizes. All it takes, then, is to delete all the log files, which will not impact your game negatively, and see your game’s performance improve, or at least, not crash anymore, all due to a quick task to clear cache files.

Other Ways To Boost League of Legends Performance

Of course, League of Legends is not only influenced by its own log files. It also depends on your hardware, internet connection and regular patching. So, there are a few more ways to boost your League of Legends gameplay experience aside from clearing cache files.

Closing League of Legends Client

One of the reasons you are disconnecting mid-match, or have a low FPS, while you play League of Legends can be due to the Client. Riot Games have thought of that, though, and offered a solution:

  1. Open the Client Settings Menu,
  2. Open the General Options
  3. Select settings under the “Close Client during game” tag
League of Legends - Client Options

By doing so, you ensure that nothing from the League Client will cause you to randomly disconnect in the middle of the game, due to some Riot Games processes randomly put in the Client.

Closing Background Applications

Closing the League of Legends Client is something that needs to be done before the game starts. However, a quick fix can be done by closing background processes in the Task Manager, that use up a lot of your bandwidth:

  1. Open task Manager
  2. Click on More Details
  3. Open the Processes Tab
  4. Click on the Network Tab to list processes by their network usage
  5. Close all background apps that use too much bandwidth

It is unlikely that this will solve the issue if you have been randomly disconnected without noticing your ping spike in the game beforehand, or just having a stable ping to play better. Still, it’s worth a shot, especially for those whose internet connection is bad as is.

Initiating Full Repair

If none of the above solutions worked, it is time to try one that is more lenghty, but can still be done and tied to League of Legends exclusively. That is initiating the full repair option in the LoL Client:

  1. Open the LoL Client
  2. Open the Settings
  3. Open the General Tab in the Menu bar
  4. Initiate Full Repair
League of Legends - Full Repair

This fix can only be done after a game has finished, though, as you are unable to access the Client features fully while the game is in progress.

Using Hextech Repair Tool

One of the issues that can impact the performance of League of Legends, is the game files of said game. The most thorough solution is reinstalling League of Legends from scratch, but that is not always needed.

League of Legends - Hextech Repair Tool

Instead, Riot Games have developed the Hextech Repair tool which finds corrupted game files and takes care of them, freeing up valuable disk space and is a more thorough version of clearing your Client Cache logs. As it does so, Hextech Repair Tool will either force a repatch, automatically download clean game files, or, if the problem is too far gone, have a freshly installed League waiting for you:

  1. Launch Hextech Repair Tool
  2. Select your region
  3. Enable all options
  4. Check the Firewall to give it a firewall exception
  5. Click on the “Press Start” button
  6. Restart your computer upon finishing

If the Hextech Repair Tool is unable to solve the issue for you, then it compiles all the application data it found and offers you the option of making a ticket and sending it to Riot Games player support for League of Legends, where you will be offered additional options.

Resetting Network Settings

As the game client works off of worldwide servers, one of the ways to boost performance is by fixing a faulty internet connection. Luckily it is a simple enough thing to reset, not even needing you to step away from your computer and touch a power cable:

  1. Right-click the Start Menu Button
  2. Select Settings
  3. Select Network & Internet
  4. Click on Network Reset Under Advanced Settings
  5. Reset Network settings
  6. Restart your PC
Network Reset

Once you've completed all of these if there was an issue with your internet League of Legends should work better than it used to.

Resetting Your DNS Server Adress

One thing that can impact your League of Legends performance can also be caused by an issue with your DNS. That is, the connection it carries. The fix League of Legends needs is a reset and getting an alternate DNS server:

  1. Open Run by pressing the R Button + Windows key.
  2. Type in ncpa.cpl and click OK
  3. Right-click the network adapter and select Properties.
  4. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
  5. Tick the Use the following DNS server addresses option.
  6. Type in 1.1.1.1 in the Preferred DNS server.
  7. Type in 1.0.0.1 in the Alternate DNS server
  8. Save changes by pressing OK
  9. Restart your PC
DNS Restart

With this, if the cause of League of Legends not working properly is your DNS, then it should be solved upon a quick restart of your PC and having the changes applied.

We must caution that even a clear cache will not take care of all your crashing issues, but will make the game run more smoothly.
