Over time some League of Legends players experience seemingly random drops in frame rates. Although the reasons vary greatly, here are a few of the most common issues: a patch installs incorrectly or implements a new rendering technique, a new piece of software is slowing down your system or you are in need of a driver update.



Troubleshooting FPS Problems
Symptoms:
Game appears choppy
Screen freezes for small periods of time
FPS in upper left-hand corner is lower than 24
Latency problems commonly mistaken for FPS issues
Game delays or stops receiving input
Champion appears to teleport around the map
Game runs in fast motion
You can troubleshoot latency problems in the guide here.

Solutions:
[Emergent Issue] Riven Patch - September 15th
Some players have noticed a dramatic reduction in frame rate since our latest patch with Riven. We are looking into possible causes and fixes for this but there are a few workarounds that you can use while we track down this bug.

Many players have been able to remedy this problem by doing one of the following as a temporary workaround:

Set LolClient.exe to "Low Priority" after logging in
At the start of each game set "League of Legends.exe" to High Priority
You can view a guide on modifying your priority here.
Alt-Ctrl-Del at the beginning of the game and close LolClient.exe
Warning: This closes the PVP.Net chat and require you to re-login after the game is over
While these are two common solutions for players experiencing problems with the latest patch, the following will also likely help boost your FPS even higher.

Update video card drivers [#1 Solution]
Manufacturers of video and graphics cards frequently release bug fixes and optimizations for their cards. These optimizations come in the form of drivers which you can download from the manufacturer. This subject is so important that I have written an entire guide on this subject located here. Although this section of the guide is short, getting the most updated proper drivers for your system is the single most important thing to you can do to improve your framerate.



Change game settings [#2 Solution]
The Video options you choose in game have a large affect on your FPS. By selecting less complicated video rendering you can improve your FPS. To access these options once in-game press ESC and select Video. You can view a detailed description of these settings at the bottom of this guide.

Settings for best performance:
Settings: Custom
Resolution: Match desktop resolution
Character Quality: Very Low
Environment Quality: Very Low
Effects Quality: Very Low
Shadows: No Shadow
Fast Terrain: Unchecked
Frame Rate Cap: Benchmark, 25 FPS or Stable (depending on hardware)
Wait for Vertical Sync: Unchecked or Checked (depending on hardware)

To make this easier for you we have added a file that will pre-set these options by replacing it with the file in this directory:
game.cfg

C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\release s\"latest version"\deploy\DATA\CFG



Tune-up your PC:
Like a car, there are small things that each person should do to keep their PC in tip top shape. When you have FPS issues doing a tune up is one of the easiest ways to increase performance. Many of these tasks can be performed by free software packages. I will note several times during this section of the guide that the software is created by a 3rd party and Riot Games cannot be held responsible for its use. This isn't meant to scare you away from the software, simply to inform you that we are not the makers of the software and do not support it. I always post these links with their full URL.

Scan for malware:
Malware builds up on players systems. Usually it is installed without the users permission and is intended to steal personal data. There are many free scanners on available on the internet for home use(they make money selling premium versions). Although we have no affiliation and can't be held responsible for the software we recommend Malware Bytes: http://www.malwarebytes.org/

It is a good idea to remove software such as Microsoft Security Essentials or Spybot Search and Destroy. These applications remove malware but also have a real-time protection component that slows down many systems. In many cases, they end up doing more harm than good.

Uninstall unused programs:
Many times players install programs to either try them out or use them for a specific purpose. Often, we forget to remove such programs. Please take the time to go through your Add/Remove program list to remove any unwanted or unused programs. Doing so will free up more system resources for the game to use.

If you are unfamiliar with uninstalling programs in Windows feel free to reference this guide(on a 3rd party site): http://kb.iu.edu/data/aixt.html



Modify graphics card software settings
Nvidia comes with the Nvidia Control Panel and ATI comes with the Catalyst Control Center. Both of these programs allow users to set up graphics profiles that can interfere with the FPS of League of Legends. Many times this can occur after a driver or windows update. Please read this guide on how to return them to the proper settings.

[Windows Vista or Windows 7 Users]Disable Aero
Aero is a new feature of Vista and Windows 7. It included many new advancements in the Windows GUI. Including: transparent windows, Win Key + Tab option and window transitions. Unfortunately all these new features tend to slow your computer down. Aero tends to especially have a negative impact on netbooks or laptops.

To Disable Aero:
Start > Search "Aero" > Windows Color and Appearance > Advanced appearance settings... > Select non-Aero theme.



Repairing corrupt game files
Occasionally FPS problems can be caused when certain game files become corrupt. For this reason, using the repair function in the Patcher is a good idea if you begin to experience problems with the in-game FPS.

To run the repair function:

Run League of Legends
Click on the button with a gear near the top of the window.
Click Repair.
Wait. The repair function can take anywhere from 5 minutes to over 30 depending on the number of corrupt files it has to repair(redownload).
Set Windows to best performance
Older systems may not be able to render the advanced graphical features of Windows and those of League of Legends at the same time. You can turn off many of these advanced graphical features provided by Windows to improve your system performance. While older machines will see the most benefit even relatively modern PCs may see a performance increase by changing this setting.

Instructions:

Right-click Computer
Select Properties
Select Advanced System Settings
Select the Advanced tab
Click Settings under Performance
Select the Adjust for best performance radial
Move to the Advanced tab
Select the Adjust for best performance of: Programs radial

Remove Resource hogs
Every PC has a limited number of resources. Each program takes up RAM and CPU time. If you have many programs running they will use resources that could otherwise be used by League of Legends to speed up the game.

Common Resource Hogs
Anti-Virus: Norton, Symantec, Kapersky, McAffee, AVG

Browsers: Internet Explorer, Firefox, Google Chrome

Chat programs(especially video chat): Skype, MSN Messenger

Bloat ware: This is software installed on your computer by default. Most of it provides no value and simply consumes resources



Check for heat issues
Does the game work fine for a game or two and then start to slow down? The most likely cause is your graphics card overheating. There are a few things you can do to make sure you graphics card does not overheat.

Buy a laptop cooler. These can be purchased for about $20 at your nearest computer supply shop. They are simply external fans that can be plugged into a wall outlet or USB drive depending on the model. They are very effective at keeping laptops cool.

Clean any vents or fans with compressed air. Often older machines get their fans clogged with dust, dirt and hair. Cleaning the vents and fans of your PC will improve airflow and make your machine at a lower temperature.

Advanced Solutions
Clean your registry:
Each time a program installs it makes modifications to the system registry. Overtime, the registry can become bloated. Usually this is not a problem but it is an easily resolved problem. Again, there are many free programs available on the internet.

Our personal recommendation is CCleaner. This program is neither created nor endorsed by Riot Games and we cannot be responsible for its actions.

Defrag your hard disk drive:
Hard drives work like filing cabinets. When you constantly add and remove files from them they become disorganized and it is more difficult for your computer to locate the correct file. In fact, files are sometimes split into small pieces and scattered among the drive. To resolve this problem you need to de-fragment your main hard disk. Here is a guide by Microsoft to performing this on a windows machine: http://www.microsoft.com/atwork/maintenance/speed.aspx#3



Detailed settings descriptions:
You will notice each card has Best Performance/Visuals categories as well as balanced. Balanced are the settings that I have found work well with most Dedicated Graphics cards such as the Nvida Geforce 6800 or better.

Resolution:
Best Performance: Match desktop resolution or 1024 x 768
Best Visuals: Highest available that matches the aspect ratio of your monitor.
Balanced: Match desktop resolution

This is the number of pixels you will render on the screen. 1024 x 768 is 750,000 pixels. However 1920x1080 is over 2 million.



Character Quality:
Best Performance: Very Low
Best Visuals: Very High
Balanced: Medium

This is the quality of the models that are rendered in game. By lowering this setting the game uses lower poly models.



Environment Quality:
Best Performance: Very Low
Best Visuals: Very High
Balanced: High

This affects the quality of the terrain in the game. Higher settings add details such as blades of grass, flowers, mushrooms, lamp posts and other such flourishes to the map.



Effects Quality:
Best Performance: Very Low
Best Visuals: Very High
Balanced: High

This affects the quality of the spells and abilities in the game. Lower settings restrict the number of particles rendered by each spell or ability cast.



Shadows:
Best Performance: No Shadows
Best Visuals: Very High
Balanced: No Shadows

This affects the quality of the shadows on the characters and towers. Lower quality results in jaggy or non-existent shadows. Higher quality creates smoother shadows.



Fast Terrain:
Best Performance: Unchecked
Best Visuals: Unchecked
Balanced: Unchecked

Fast terrain is an option that may boost performance on older cards. However, it disables the zoom feature of the game, changes the camera angle and can result in a few graphical artifacts. For example: Fog of War may update late, buildings may disappear, trees and other parts of the terrain may appear black.



Frame Rate Cap:
Best Performance: Benchmark, Stable, 25FPS
Best Visuals: Benchmark
Balanced: Stable

League of Legends is capped at 100 frames per second. Benchmark allows League of Legends to run at max frame rate. However, choosing stable or 25 FPS may produce a more consistent FPS on older graphics cards.



Wait for Vertical Sync:
Best Performance: Unchecked (for most cards)
Best Visuals: Checked
Balanced: Unchecked

This option restricts League of Legends frames to your monitor refresh rate(usually 60HZ). Some graphics cards flourish with this setting but many can generate higher FPS with it off. Leaving the option off may produce tearing on your screen where a shifted line appears in the middle of your screen. For the best visuals you should leave it on.

Yeah, setting your "LolClient.exe" Priority to "Low" is NOT A GOOD IDEA.
If you do that, then it will sometimes crash your game :\
It kinda sucks.
