Symptoms

The technical performance of each of your games is stored in a file called a log. Specifically, r3d logs can help pinpoint issues related to hardware and software. You can upload your r3d logs to this tool to learn how to solve these kinds of issues:

  • Unexplained drops in FPS (the game seems to slow down)
  • Hitching, stuttering, or skipped frames (the game stops and starts a lot, especially during teamfights)
  • Crashing to desktop mid-game
  • Odd artifacts or visual bugs while in-game
  • The game closes and gives you a bug splat error

Sound familiar? The automatic tool below can help. Just track down your r3dlogs (locations below), and submit them to the tool, which will read the logs and explain what went wrong during the game. This tool will also display to you (and only you) information about your hardware that is gathered from the log you upload to help troubleshoot issues. This information is not gathered or stored.

 

r3dlogs are located here by default:

  • Windows: C:\Riot Games\League of Legends\Logs\Game - R3d Logs
  • MacOS: Click the "Upload Logs" button, press ⌘-Shift-G, and paste in: /Applications/League of Legends.app/Contents/LOL/Logs/Game - R3d Logs

DETECTED ISSUE: CRASHING INCONSISTENT/LOW FPS

It looks like League crashed on you during this game. Crashes can be caused by several different issues, but based on the log, we can offer a few likely solutions.

It looks like your framerate this game was unstable. A consistent 60 FPS is optimal, but this game your average FPS was X, and your minimum FPS was Y. Inconsistent FPS can be caused by several different issues, but based on the log, we can offer a few likely solutions.

It looks like your hardware meets the minimum requirements for League of Legends(yay!), so we shouldn't have to do any hardware upgrades. However, we can't check your CPU speed to ensure it meets the requirements as well, so double check here to make sure your processor is able to play League. While your graphics card meets the minimum specs, it does not match the recommended specs. We strongly recommend setting your in-game graphics sesttings as low as possible to prevent lag and crashes. 

Unfortunately, it appears your hardware may not meet the minimum requirements for League of Legends. Specifically, the log indicates you had below the minimum RAM requirement of 1GB, and your CPU speed was below the required 2.0 GHz. You can check out the minimum requirements here. For the best performance, we recommend upgrading your hardware to meet these requirements.

It appears that your version of Windows may be out-of-date. To double check, hit "Start", type "Windows Update", and check for the latest security and stability updates. Optional updates aren't necessary, but any updates Windows marks as required will be necessary to run League of Legends.Unfortunately, it looks like your version of Mac OS is out-of-date. From the apple menu, select "System update" and be sure to check for the latest updates available.

Your graphics card is currently using the latest drivers, so no driver updates are required. If you wish to double-check, you can find the latest graphics card drivers hereherehere.

We were unable to check your graphics card driver version, so be sure to check if there's a new driver for your graphics card hereherehere.

You may not have the latest drivers installed for your graphics card. This can cause a variety of issues, not just for League of Legends. Try doing a full, clean install of the latest drivers for your graphics card (found hereherehere). 

Your version of WindowsMac OSX seems to be fully up to date, so you shouldn't have any issues there. Individual updates may be missed by this log reader, so be sure to fire up Windows UpdateMac's System Update to check that you're fully up-to-date.

DETECTED ISSUE: FIREWALL PROBLEMS

This log indicates that your firewall is blocking League of Legends traffic. R3dlogs don't have a lot of network-related information, so your best bet to dig into this further is to check out our netlog reader here. The netlog will provide detailed information on network conditions during your game. Both network and hardware issues can look the same, so it's useful to look into both logs to investigate the source of an issue.

You can also use the Hextech Repair Tool to automatically add exceptions to your firewall for League traffic!

NO ISSUES DETECTED

This log contains no issues; it appears that this game went smoothly from a hardware perspective. It's possible that a connection issue caused trouble this game, which a r3d log wouldn't pick up. To check the network stability of this game, you can check out our netlog reader here. Both hardware and network issues can look the same, so it's useful to look into both logs to investigate the source of an issue.
