How To Fix Halo 4 UE4 Fatal Error

Errors and issues are bound to crop up in PC video games and Halo 4 is not immune to it. Players are reporting that they are experiencing a random in-game crash while playing Halo 4 with error messages such as UE4 Fatal Error, D3D Device Lost, and more.

There are a number of reasons behind the Fatal Error crash and here is how to fix Halo 4 UE4 Fatal Error.

UE4 Fatal Error Crash Fix

One reason behind the Halo 4 UE4 Fatal Error Crash is the Fullscreen mode. Go to your Steam library > right-click Halo MCC > Properties > click “Ser Launch Options” > type ‘-windowed’ and press ok. Launch the game and it’ll run in Windowed mode and won’t crash.


If the above fix doesn’t work for your then, navigate to C:\Users\’your username’\AppData\LocalLow\MCC. Backup all the files and folders you find here and delete all of them. Go to Steam and verify game files for Halo MCC. After that, launch the game and it won’t crash.

Those of you facing the Fatal Error on Windows 7, download and install this update and the error will be fixed. If the error persists, installing the update KB3080149 will fix it.

If Halo 4 is crashing with a Fatal Error message, then the issue might be the GPU. Either the GPU is overclocked, old, or is putting an unreasonable load on the GPU. If the GPU is overclocked then revert it back to its default GPU clock even if it’s factory overclocked. In case the GPU is old, then use MSI Afterburner and reduce the GPU clock by 100 MHz. Ideally, you won’t have to drop it more than 200 MHz.

In case you don’t want to mess with the GPU clock, then they can fix this error by locking the game’s FPS. If you are playing it at unlocked FPS then limit the game to 60 FPS. In case you are playing the game at 60 FPS, open Nvidia Control Panel > Manage 3D Settings > Program Settings > Select the game. Enable “Max FPS Limit” and set the value to 30. This will limit the game to 30 FPS and will reduce CPU and GPU load. After this, Halo 4 won’t crash with UE4 Fatal Error.
