Fix #3 – Windows 10 64-bit is mandatory for Mafia Definitive Edition

The PC version of Mafia Definitive Edition does not support any other OS other than Windows 10, that too the 64-bit version. So if you have a different OS installed then you are out of luck here. Neither this game will run on Windows 7, nor will it run on Windows 8.1 or Linux. I know this is not really a fix, but this is something everyone should know.

Fix #4 – Verify the in-game files of Mafia Definitive Edition on Epic Launcher

Fix #6 – Whitelist Mafia Definitive Edition on your Anti-Virus Software

Anti-Virus software hooks very deep into user systems and can affect disk and network operations which can cause crashes in games. Some games also use copy protection technology that can appear as malicious software to an AV scanner, resulting in potential false-positive alerts.

Try disabling your Anti-Virus software temporarily and then run Mafia Definitive Edition. It may also be necessary to add exceptions for Mafia Definitive Edition in your AV configuration.

If you are using Windows Defender instead of a third-party AV software then here is how to add Mafia Definitive Edition on the exceptions list of Windows Defender:

  • Go to Windows 10 settings
  • Click on Update & Security
  • Select Windows Security from the left sidebar
  • Click on Virus & threat protection
  • Under Virus & threat protection click on Manage settings
  • Under Exclusions click on Add or remove exclusions
  • Click on Add an exclusion
  • Select File
  • Select the .exe or executable file of Mafia Definitive Edition
  • Restart your PC

Fix #7 – Close any sort recording or overclocking utilities

Close any kind of recording or overclocking utility that is running on your PC. Overclocking applications like the RivaTuner or MSI Afterburner, are causing crashes for a lot of games. Sadly, Mafia Definitive Edition is one of them. Even the slightest change in the base memory clock or core clock via an overclocking application is causing the game to crash after few minutes. A lot of games had the same problem. So it is better to stay on the safe side

Fix #8 – Update your OS

The DirectX issue could be related to your Windows 10 version. Windows 10 updates cannot be trusted. The recent Windows 10 updates have already caused loads of problems for a lot of AAA titles. The Windows 10 KB4512941 update that was released few months ago gave some serious trouble to gamers all over the world. From high CPU usage to constant stuttering while playing games or running heavy applications, people had to face everything.

Thankfully, Microsoft has already released an update that fixed the problem mentioned about. But who knows, there might still be some users who have not updated their Windows since then out of fear and are still facing performance issues. So check whether you have pending Windows updates or not and then update your OS. Here is how to do it:

  • Go to Settings
  • Go to Update & Security
  • Click on Check for updates
  • Wait for the updates to get installed
  • Restart your PC
