  • Make sure your computer meets the Minimum System Requirements.
  • Make sure your display settings are set properly.
  • If you can’t get in, you can also change your resolution out of game by navigating to the following location of your League of Legends installation:
  • Local Disk --> Riot Games --> League of Legends --> Config
  • Once here, you will find a file labeled ‘game.cfg’
  • When you open this file, under the [General] section will be:
    • Height: XXXX and Width: XXXX.
  • This works exactly the same as your resolution settings on windows and can be changed to the values you specify.
  • Check the Bug Splat and Game Crashes article in the knowledge base

Why am I getting 0-5 LP for a win? / Why am I losing more LP for a loss?

This is known as clamping, and occurs when you’re up for a Tier promotion but your Matchmaking Rating (MMR) is far lower than expected. You can read a bit more about how and why this happens in the 2014 Season FAQ.


I won a game but lost LP / I lost a game but still gained LP

This is a visual display bug that can occur when the LP system is delayed. You did not actually lose LP for a game you won, it’s just showing a previous update, and you will still get your points as normal.

Graphics Troubleshooting

See the ideal settings in the KB.


Players jump around/go fast

In your in-game settings, switch Movement Prediction to “off” If the above didn’t work, it’s likely a connection issue. See the connection issues information below.


I can’t see the ground/champs / Fog of War covers everything / I get artifacts/flickering on the terrain

  • Make sure that your graphics drivers are completely up to date
  • For Mac (Apple) users – Make sure you have no Razer programs (like Razer Synapse) running in the background, if you do, disable them.
  • For PC (Windows) users – Make sure that the Debug version of your DirectX is deactivated
  • ATI(AMD) and nVidia control panel settings may be overriding your graphics. Try making sure all 3d settings in those programs are set to “Application Controlled” and turn off any V-Sync settings.

I’m a left hander / How do I use the keypad?

  • You can add these to [GameEvents] (create it if it doesn’t exist) in the input.ini file (default location, C:\Riot Games\League of Legends\config)
  • evtScrollUp = [Num8]
  • evtScrollDown =[Num2]
  • evtScrollLeft = [Num4]
  • evtScrollRight = [Num6]
  • IMPORTANT: Make sure not to modify the input.ini file under “default” as that will break patching. Modify the one in:
  • League of Legends\RADS\solutions\lol_game_client_sln\release s\0.0.0.###\deploy\DATA\CFG
  • and add one if it doesn’t exist. You can use the one under defaults as a guide.

I can’t get into the game to change my graphics settings.

I have bad FPS in game


The mouse pointer / menus are slow

  • You may have an integrated graphics card which doesn’t run as well.
  • Turn off any running anti-virus scan or other program using lots of resources.

I lag in game

  • Stop any active downloads or streaming services. These tend to use a lot of bandwidth.
  • Powercycle (restart) your modem and router.
  • Try plugging directly into your modem if you use a wireless router.
  • Disable Peer-to-Peer transfers in the patcher (gear icon top right, save settings, restart PC)
  • Uninstall Pando Media Booster
  • Control Panel -> Add/Remove Programs
  • Reinstall your network card drivers.
  • Check with your ISP about outages or blocking.
  • Try some of the steps listed in this knowledge base article.

I always get disconnected in the middle of the game

  • Navigate to C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\release s\0.0.0.xxx\deploy (This is the default directory) and look for League of Legends.exe - take this icon and place it on your desktop and rename it to “Quick Reconnect” to rapidly launch the game again without patching, if you get disconnected.
  • Check to see if you can still get online somewhere else.
  • Check your router settings or try plugging directly into your modem.
  • If you are still experiencing issues, try running through the steps listed in this knowledge base article.

I’m still connected, but I can no longer move or do anything

  • Disconnect and reconnect to the game. You may have to shut down the client

I got disconnected and have Game Still In Progress, but can’t reconnect

  • Wait 20-30 seconds and try again
  • The server may have crashed in which case everything’s going to be borked for a little bit. Come back in an hour and try again.

I see myself stop moving, then people jump around and move really quickly like the game is catching up.

  • This is most often a connectivity issue. Make sure to follow the steps in this knowledge base article. You may also need to contact your ISP for assistance.
