FAQ

My game isn’t starting / is crashing / behaves strangely

Try one or more of the following steps:

  • Verify your local files through Steam.
  • Open regedit and delete Computer\HKEY_CURRENT_USER\Software\Valve\Source\iosoccer.
  • Uninstall the game through Steam, delete the IOSoccer folder (e.g. C:\Program Files (x86)\Steam\steamapps\common\IOSoccer), and re-install.
  • Make sure your drivers are up-to-date and you have the latest Windows updates.

I have problems with alt-tabbing

If you use Windows 10 turn off the new focus assist (Windows key -> Configuration (:gear:) -> System -> Focus Assist -> When I’m playing a game -> Off).

How can I use borderless windowed mode (aka windowed fullscreen)?

Add -noborder -window as launch parameters.

What other launch parameters are there?

Many (but not all) of the parameters listed here should work.

I have a low framerate

Changing the console variable mat_queue_mode from -1 to 2 should give you an FPS boost.
Warning: Your game will most likely crash when using this setting and alt-tabbing while in fullscreen mode.
Using (borderless) windowed mode can fix this issues. Alternatively change the variable back to -1 whenever you need to alt-tab.

My resolution isn’t in the drop-down list

Make sure you set the correct aspect ratio in the list below it.
If it still doesn’t show up you can use the launch parameters -width x -height y.

Known issues

  • The game can’t load non-ASCII player names from the config (SDK 2007 engine limitations)
  • The server often crashes when restarting the match after final whistle
  • The server hangs when changing maps sometimes
  • Replays aren’t smooth and show players twitching
