3. Uninstalling

   To uninstall DiRT 4, follow these steps:

   1. If it is not already running, launch the Steam application.

   2. Select the Library tab.

   3. In the library, right-click on DiRT 4 in the list of games on the left-hand side of the window, then select Manage → Uninstall.

   4. A dialog will appear confirming that you wish to delete all the game content. Select Uninstall.

   
   You may also wish to remove the DiRT 4 preferences, which are stored in the feral-interactive folder in your computer's ~/.local/share folder (where the "~" symbol refers to your home directory). Deleting the preferences folder will remove the save files, so all game progress will be lost.

   NOTE: By default, the .local folder is hidden from Files. Press Control (ctrl) + H to reveal hidden folders.

   NOTE: If you have more than one game from Feral installed, remember to check inside the folder so that you do not delete preferences for other Feral games.

5. DiRT 4 Performance Tips

   The most important factors in determining how smoothly DiRT 4 plays are your CPU speed, the amount of built-in RAM, the type of graphics card in your computer and the in-game settings you select.

   DiRT 4 is playable with the minimum specifications listed below, but it will play more smoothly on faster computers with more RAM. However, if you are dissatisfied with the performance of the game on your computer, there are a couple of things you can do that are likely to improve performance:

   • Close all other applications: You are strongly encouraged to quit all other applications before launching DiRT 4 – other applications drain resources and slow the overall system performance.
   • Clear disk space: Ensure that your main hard disk has plenty of spare disk space.
   • If you have a second monitor, disconnect it (having an additional monitor connected to your Mac may create a drop in performance).
   • If you are using a laptop, plug in your charger (running on battery power may create a drop in performance).

   
   In addition to these general Mac actions, there are numerous specific in-game settings you can select to speed up the game. These are listed below in order of performance improvement (largest improvement first). Move down the list adjusting settings until you find an acceptable balance between performance and graphics.
