Clear Local App Data Folder

  1. Go into C:\Users\Username\AppData\Local\MK12
  2. Create a copy of this folder
  3. Delete the folder under C:\Users\Username\AppData\Local\MK12
  4. Launch the game to confirm if the game crashes once again.

If you recently installed a new game update and the above suggestion does not help, we also suggest attempting a clean install through the steps provided below.

Clean Installation

If you have file modifications installed and you're experiencing crashes after a game update, we suggest removing those modifications and deleting the game install folder. You can do so in each platform through the menus mentioned below:

Steam

  • Library > Mortal Kombat 1 > Right-Click > Manage > Browse Local Files

Epic Games Store

  • Library > Mortal Kombat 1 > Left-Click the 3 Dots (...) > Manage > Installation: Left-Click the Folder Search icon

After deleting the installation, reinstall the game client through Steam or Epic Games Store.

Outdated or incorrect/corrupted video and/or sound card drivers

First, make sure you have the most up-to-date video and sound drivers available for your system. Often you can find these by checking your system manufacturer's website and visiting the driver update page for your system model. You can also download updated drivers directly from your video or sound card manufacturer if you know what type of card it is. AMD and NVIDIA also offer "automatic driver" installations if you know you have an AMD or NVIDIA card but do not know what the model is.

Direct X Updates

Direct X is the software that the game uses to communicate with your PC and, if it is out of date, it can cause crashing and other issues with the game. Direct X is updated via Windows Update.

You can check for Windows Updates manually by using the steps below:

  1. Select the Start button on your PC
  2. Select Settings> Update & Security > Windows Update
  3. Select Check for updates.

You can review more information about using Windows Update here.

Overclocking or Turbo Boosting Components

If you are Overclocking or Turbo Boosting a component in your computer, such as your video card, we strongly recommend resetting the component or components to manufacturer specifications. Doing so may prevent crashes from occurring.

Corrupted Game Installation

You may have a corrupted installation of the game client. You can use the steps below to verify the integrity of your game installation. This process will confirm that all expected files for the game are intact.

  1. Go to "Library" in Steam.
  2. Locate the title in your list of games, right-click it, and select "Properties".
  3. Click the "Installed Files" tab.
  4. From here, select “Verify Integrity of Game Files”.

If needed you can also try uninstalling and reinstalling the game:

  1. Open Steam and click on "Library".
  2. Right-click the game and select "Uninstall".
  3. After the process completes you can reinstall the game by left-clicking on the game name within your Library and selecting "Install" from the game page that appears.

Settings Related Performance

Higher settings increase the workload for your system’s hardware overall, even if your system exceeds the minimum specifications for the game. 

Minimum system requirements are a list of what base hardware the game will need to function but typically on a reduced graphics settings profile.

Even if your system is within the minimum to recommended specifications for a game, options enabled that positively affect rendering quality can conversely and negatively affect performance and stability.

Using a reduced settings profile for graphics related features in the "Options" menu in-game is recommended if you are experiencing impacts to performance and/or stability.

Keyboard RGB Settings

If your keyboard supports special RGB settings then these may cause performance issues to occur while launching, loading into, and/or playing the game. To alleviate these issues, you can temporarily disable these special color settings by editing the following configuration file:

  1. Go into C:\Users\Username\AppData\Local\MK12\Saved\Steam\Config\WindowsNoEditor.
  2. Find "Usersettings.ini" and open this file in Notepad.
  3. Set "RGBPeripherals" to "off" and "RGBKeyLighting" to "off".
  4. Save Usersettings.ini.

Antivirus Related Issues

If you're experiencing difficulties with launching games on your PC due to issues caused by Antivirus software quarantining game files, this can be resolved by adding the effected title to your exceptions list.

 

Other Applications

Games in general require significant system resources, try closing down as many extraneous applications as possible before launching.  Review your antivirus support page or help for a "gaming mode" or similar option and enable that prior to play.

In some rare instances, you might want to also try what is known as a “clean boot” of Windows.  This is a temporary step and usually just to determine if, by closing down all non-Windows specific applications and startup items, there is any change to the game’s performance or stability.  After testing the game's performance, the clean boot steps should then be reversed and Windows restarted normally.

Official Microsoft steps on how to perform a “clean boot” are available here, but please follow those directions very closely because if done incorrectly you can affect the system's ability to start up. 

If the issue persists after trying the steps above, we suggest checking to see if there are similar reports on our Mortal Kombat 1 bug-reporting website at: https://mortalkombat1.bugs.wbgames.com/

If you find a bug entry that matches your issue, we encourage voting on that issue and adding any screenshots, videos, or any details you think might help with reproducing it.
