7 fixes for League of Legends lag issue

Here’re 7 fixes that have helped many LOL users solve their lag issues. You don’t have to try them all; just work your way down the list until you find the one that works for you.

Fix 1 – Modify your game settings

Fix 2 – Verify if your PC meets the minimum system requirements for LOL

Fix 3 – Update your graphics/network card drivers

Fix 4 – Stop unnecessary processes

Fix 5 – Delete temporary files

Fix 6 – Adjust your Windows settings

Fix 7 – Swap Wi-Fi to an Ethernet connection


Fix 1: Modify your game settings

When you’re experiencing LOL lag spikes, the first thing you should do is to modify your game settings. Here are the steps:

1) After launching LOL, click on the icon which looks like a gear in the upper right of your game screen.

2) Here pops up the CLIENT/GENERAL window. Select GENERAL from its left pane. Then, make sure you check the following two boxes in the right section: Enable Low Spec Mode and Close client during game.

Click DONE to save the changes.

3) Log in your account and start a new game.

4) Press Esc on your keyboard to open the settings window. Here’s a list of tweaks you should make:

  • In the left pane, select VIDEO. Then turn to the right and open the drop-down list of Resolution. Generally you’re recommended to select 1280×720 from the list.
You may choose the resolution that suits your PC best. For example, if you still can’t run the game properly at 1280×720 , then drop to 1024×768. Follow the same testing steps until you find the one that works for you.
  • Check these two boxes: Colorblind Mode and Hide eye candy.
  • Roll the slider below Graphics to Medium, Medium Low, Low, or Very Low according to your conditions.
  • Check the Character linking box.
  • Open the drop-down list of Frame Rate Cap below Advanced and then select Uncapped.
  • Uncheck the Anti-Aliasing and Wait for Vertical Sync boxes.

Click Okay to save the changes.

If this method cannot help you solve the LOL lag problem, you should read on and check out the rest of the fixes below.


Fix 2: Verify if your PC meets the minimum system requirements for LOL

If adjusting your game settings won’t do the trick for you, then you should check if your PC meets the minimum system requirements for LOL.

Here’s the minimum system requirements for LOL:

  • The minimum system requirements for League of Legends
Operating System: Windows XP (Service Pack 3 ONLY), Windows VistaWindows 7Windows 8, or Windows 10
Processor: 3 GHz processor (supporting SSE2 instruction set or higher)
Memory: 1 GB RAM (2 GB of RAM for Windows Vista and newer)
Graphics: Shader version 2.0 capable video card
Resolution:
Up to 1920 x 1200
DirectX: DirectX v9.0c or better
Storage:
12 GB available hard disk space

If your PC barely meets the minimum system requirements for LOL, you’re not likely to enjoy the best possible gaming experience. So here’s the recommended system requirements for your reference:

  • The recommended system requirements for League of Legends
Operating System: Windows XP SP 3Windows VistaWindows 7Windows 8.1, or Windows 10 with the latest service pack installed
Processor: 3 GHz dual-core processor
Memory: 2 GB of RAM (4 GB of RAM for Windows Vista and higher)
Graphics: Nvidia GeForce 8800 AMD Radeon HD 5670 or equivalent video card (Dedicated GPU with 512 MB or higher Video Memory (VRAM))
Resolution:
Up to 1920 x 1200
DirectX: DirectX v9.0c or better
Storage:
16 GB available hard disk space

If your computer meets the minimum or even recommended system requirements for LOL, move on to the next fix. Otherwise you should try to upgrade your hardware devices first.


Fix 3: Update your graphics/network card drivers

Outdated or corrupt drivers can be a large detriment to your FPS (Frame Per Second) and even cause major lag spikes. To fix the LOL lag issue, you should update your graphics/network card drivers to the latest versions.

If you don’t have the time, patience, or computer skills to update the drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. Driver Easy takes care of everything.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks.

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

Note: you can do it for free if you like, but it’s partly manual.

In case your LOL lag problem hasn’t been solved, try the next fix. But do keep in mind that updating drivers can improve your PC performance for gaming.


Fix 4: Stop unnecessary processes

Here are the steps for you to stop the unnecessary processes while you’re playing LOL.

1) On your keyboard, press the Windows Logo key and R at the same time to invoke the Run dialog box. Type in taskmgr and hit Enter.

2) Select the Processes bar. Right-click on the unwanted process such as Google Chrome to open its context menu. Then click End task.

Do not close the processes which you’re not familiar with in case you mistakenly stop the important ones.

3) Disable your antivirus software temporarily. This is optional for you but you can give it a try and see if that mitigates your lag problem.

Note that Microsoft has its own default anti-malware, Windows Defender. It’s automatically enabled even if you also have other antivirus applications installed. Even if you disable your other antivirus programs, Windows Defender is always there for you during that certain time range. So, no need to worry too much about temporarily turning antivirus off. 


Fix 5: Delete temporary files

Deleting temporary files can effectively free up your disk space and even solve your lag issue in LOL. Follow the steps below and see if it works for you.

1) On your keyboard, press the Windows Logo key and R at the same time to invoke the Run dialog box. Type in %temp% and hit Enter.

If prompted, click Continue to open the folder.

2) Press Ctrl + A to select all the files. Then hit the Delete button on your keyboard to clear them up. This won’t affect your personal files.

3) Click Skip if you’re presented with a warning that says “the folder or a file in it is open in another program.”

4) On your keyboard, press the Windows Logo key and R at the same time to invoke the Run dialog box again. Type in temp and hit Enter.

If prompted, click Continue to open the folder.

5) Select all the files and delete them to clear up the folder.

6) Click Skip if you’re presented with a warning that says “the folder or a file in it is open in another program.”

7) On your keyboard, press the Windows Logo key and R at the same time to invoke the Run dialog box again. Type in prefetch and hit Enter.

If prompted, click Continue to open the folder.

8) Select all the files and delete them to clear up the folder.

9) Click Skip if you’re presented with a warning that says “the folder or a file in it is open in another program.”

10) Don’t forget to empty your Recycle Bin after all the deletion processes above finish.

You may also do a disk cleanup if you like. Please refer to the Windows support site for further information:

Fix 6: Adjust your Windows settings

Follow the steps below to adjust your Windows settings for enhanced gaming performance:

1) On your keyboard, press the Windows Logo key and R at the same time to open the Run dialog box. Type in control panel and hit Enter.

2) Under View by, click Category. Next, click on the System and Security category.

3) Select System.

4) In the left pane, click Advanced system settings.

5) In the pop-up System Properties window, click on the Advanced bar. Then click Settings… in the Performance section.

6) Select the Visual Effects tab and click Adjust for best performance. After that, click OK. (You may also click Custom and adjust settings according to your own taste.)

Adjusting your Windows settings may improve your PC performance for gaming. Please launch LOL and check if your lag issue has been solved or mitigated.


Fix 7: Swap Wi-Fi to an Ethernet connection

If none of the fixes above work for you, then maybe you should turn your eyes upon the network connection. Admittedly, a wireless network is not as stable as a wired one so you’ll get more interruption if your computer is connected to Wi-Fi. For example, when you’re playing LOL in a room far away from your router, the Wi-Fi signal you receive can be rather weak, causing the lag spikes in LOL.

To solve this problem, you’re suggested to swap Wi-Fi to an Ethernet connection, but this is not practical for everyone. As an alternative, you may buy a powerline Ethernet adapter which can extend the reach of your home network to places with poor wireless coverage. Once your network issue is solved, your lag spikes in LOL may also be fixed once and for all.

This is an powerline Ethernet adapter.

We’ll be glad if any of the fixes above help you solve the League of Legends lag issue. Please feel free to leave a comment below if you have further questions or other fixes to share. Hopefully you’ll have wonderful gaming experience in LOL and work your way up to the best player!
