8 Ways To Resolve Tf2 Steam Error 11

1 /8

Start Team Fortress 2 From Steam Client

Team Fortress 2 Steam error 11 happens most often when players start the game from their desktop shortcut. Thus, the most obvious solution, and the one that usually works is to start the game from the Steam library.

It should solve the issue of an incorrect line of code compiling into the program's source code, and allow you to play the game normally!

Update Your OS

We all hate doing it and delay it until the end of time, but you always need to update to the latest version of your Operating System to keep it working smoothly, especially if there's been a game update or Steam Client update since then, no matter if you’re using Windows or some other OS.

OS Update

New game updates can require recently added features for it to run smoothly so not installing your updates can cause problems, and here is how:

  1. Open Start

  2. Search and Click on Check For Updates

  3. Click on the Check for Updates option

This way, if there are any new updates that you haven’t come around to installing, they will download automatically. If everything is clear, then that is not the cause of this particular Team Fortress 2 Steam error message.

Update Graphics Drivers

Seeing as there is no way that your PC is unable to run Team Fortress 2 these days, or causing startup crashing issues, the issue can also be caused due to an outdated graphics card driver for your hardware and it’s a good idea to check for and install the latest video drivers.

This one is a bit tricky since every dedicated graphics card, or video card, as those are interchangeable these days, has its own drivers. It's useful for all sorts of things, however, including showing FPS in Team Fortress 2, namely the fact that it won't be dropping!

Graphics Drivers

However, usually, they all come with an accompanying app to help you keep your graphics card drivers up to speed. In the case of Nvidia, here is how to do it:

  1. Open GeForce Experience

  2. Click on the “Check for Updates” option on the homepage

If that doesn’t solve the issue of the Team Fortress 2 error "creating temporary files", then you may also want to check the drivers for sound, network, and other things that Team Fortress 2 uses to be able to run smoothly.

Verify the Integrity of TF2 Game Files

Unfortunately, there is always a chance that the problem may run deeper. So, one thing you can do is verify the integrity of your game files, and see if that fixes the issue.

  1. Open Steam
  2. Right-click on Team Fortress 2 in the Library tab
  3. Select Properties
  4. Select the Local Files tab
  5. Click on the "Verify integrity of game files" option
  6. Wait for the verification process to end
  7. Restart your PC to apply changes

Team Fortress 2 - Files Integrity

If the verification process finds something wrong with your game files, as even minor changes that are unauthorized to your game files can cause issues, Steam will automatically replace the corrupted or missing game files, to ensure the game runs smoothly.

Clear Steam Download Cache

The issue can be caused by a variety of things, and a full Steam Download Cache is one of them. Luckily, doing so is easy, and Steam even has an in-built way of doing so. It's just a question of following these simple steps.

Clear Download Cache

  • Open Steam Client
  • Open Setting in the top left corner
  • Select Downloads
  • Click on the "Clear Download Cache" option
  • Click "OK"
  • Restart Steam Client

Clearing the Steam download cache forces Steam to clear locally cached configuration data, and reacquire it from the Steam server again, hopefully resolving whatever caused error 11.

Set Proper Screen Resolution

If the previous fix did not do the trick, the issue may also be related to the famous Team Fortress 2 fullscreen problems, as somehow the software goes bonkers when the precise resolution is not set. The fix is simple

  1. Open Steam Client
  2. Right-click on Team Fortress 2 in the Library tab
  3. Select Properties
  4. Select the General tab
  5. Click on Set launch options
  6. Type in "windowed -noborder -w [SCR-H] -h [SCR-W]"
  7. Click OK

The "h' and "w" stand for the height and width of your screen. Open your PC's properties by right-clicking on the desktop, and then open Advanced Display Settings in the Display settings option.

Under Resolution, you can see your precise Screen Resolution, which you will then type in instead of [SCR-H] and [SCR-W] respectively.

If that doesn't work, you can also try out one of the best VPNs for TF2, and play on a different server, as the issue may not lie with you.

Check Steam Server Status

Speaking of the issue not being on your end, as the final precaution, you should check the Steam server status page, to see if the servers are running smoothly, both for Steam itself and the worldwide Team Fortress 2 servers.

If there are problems with any of them, you've found your culprit!

8 /8

Reinstall Steam

If even the servers are reported to be in working order, the final, end-all-be-all solution is reinstalling Steam.

  1. Open Start in the lower left corner
  2. Open Settings
  3. Open Apps & features, in Apps
  4. Uninstall Steam

Uninstall Steam

Afterward, you can just run the Steam installer again, and it will reinstall Steam for you, following which you can launch Steam, and through Steam,Team Fortress 2, just to be on the safe side as pointed out in the first solution, with no issues!

If you're using a Mac, you have to place Steam in the Trash, and then delete the Steam library from the "Library/Application Support" folder. After that, the reinstall steps are the same!
