Solved: Assassin’s Creed Mirage Unable to Change Resolution

Let us now take a look at some of the fixes to change the resolution in Assassin’s Creed Mirage.

Modify Assassin’s Mirage Config File

Modifying the game’s configuration file is one of the most common ways to resolve the resolution issue in Assassin’s Creed: Mirage. Here’s how to go about it:

Navigate to the Documents folder in File Explorer on your PC.

Navigate to the Documents folder in File Explorer on your PC. Within Documents, look for the “Assassin’s Creed Mirage” folder. Following that, proceed in the following order:

  1. The “AC Mirage” folder contains a file called “ACMirage.ini.” Click this file and choose “Open with Notepad.”
  2. Look for the lines that say “FullScreenWidth” and “FullScreenHeight” in the.ini file. Your resolution settings are determined by these lines.
  3. Change the values to achieve the desired resolution. For example, if your monitor resolution is 19201080, change the values for FullScreenWidth and FullScreenHeight to “1920” and “1080” respectively.
  4. After you have made your changes, click “File” and then “Save” to save your changes.
  5. To prevent your resolution settings from being reset automatically, right-click the “ACMirage.ini” file again, select “Properties,” and check the “Read-only” box.
  6. Click “Apply” and then “OK” to save your changes.

Change Fullscreen Mode in AC Mirage

If you are having trouble with fullscreen mode, try changing the window mode settings in the.ini file. Here are the steps to do so.

  1. As previously stated, open the “ACMirage.ini” file.
  2. In the file, look for the “WindowMode” line.
  3. The default value is “0,” which represents fullscreen mode. Change it to “1” for borderless windowed mode or “2” for windowed mode to experiment.
  4. After making the necessary changes, save the changes as before.
  5. Set the file’s properties to “Read-only” once more to keep your current window mode.

Update GPU Driver

Because Assassin’s Creed: Mirage is a new game, it’s possible that outdated GPU drivers are contributing to the resolution issue. Here’s how you can deal with it:

  • Search for the latest drivers for your specific GPU model on the official website of your GPU manufacturer (Nvidia or AMD).
  • Download and install any updates that are available. This procedure usually necessitates a restart of the computer.
  • Before starting the game, open the Graphics Settings menu by typing “Graphics” into the Windows search box.
  • Select “Assassin’s Creed Mirage’s.exe file” from the list of installed programs and set it to “High Performance.”
  • Start the game and see if you can now play in fullscreen without any resolution issues.

Verify Game Files and Reinstall

Verifying game files or reinstalling the game may also help to resolve the problem:

In the case of Epic Games:

  • Choose Assassin’s Creed Mirage from your library.
  • Click the three-dot icon next to it and select “Manage.”
  • To verify your game files, click the “Verify” button.

Ubisoft Connect:

  • Navigate to the Ubisoft Connect page for Assassin’s Creed Mirage.
  • Select “Properties” from the left-hand menu.
