Call of Duty’s Modern Warfare is an addictive game that could keep you glued for a long time. Nevertheless, it has its share of faults and errors and a common one is the Dev Error 6178. Having frustrated several players, this article aims to show you how to fix it.

What is the Dev Error 6178 Modern Warfare?

The Dev Error 6178 appears just after Call of Duty Modern Warfare crashes. This is most likely during the loading of a map on your PC or some other special feature.

Sometimes, the crash could also happen when the camera returns to the player after death. This dilemma makes the game unplayable for a lot of affected users.

What are the causes of the Dev Error 6178 Modern Warfare?

The dev error 6178 modern warfare can be caused by the following

In-Game Overlay and Nvidia Highlights Are Turned On

Two separate settings are known to trigger this particular error for a lot of users. Are you trying to engage the game with the in-game overlays and Nvidia highlights enabled? Well, turned on at the same time would propel a crash.

Outdated graphic Driver

Several users have reported that this problem came up when they haven’t updated their AMD or Nvidia GPU to the latest version. If you are in such a dilemma, you can fix the issue very easily by updating the outdated drivers via Device Manager or by using the proprietary updating software according to your GPU manufacturer.

Missing Admin Access

Well, this particular error code might show up in instances where the main game executable doesn’t have admin access.

Game is running with A Low-Tier Texture

Since its development, some of the users that are experiencing this error code are trying to fix it with Low textures. Well, if you are in a similar situation, then you should be able to fix the problem. This can be solved by using Medium or High textures instead of the lower ones.

G-sync is Responsible For The Game

You might be playing the game with a medium-spec computer and V-sync (G-sync on Nvidia) enabled. There are a few changes that the problem occurred due to the G-Sync feature.

Insufficient / Disabled Windows Pagefile

COD Modern Warfare depends on the Windows Page file quite a lot of times. If your pagefile is disabled or is configured to work with limited space, then it’s likely responsible for this particular game crash. In this case, you can resolve the problem by enlarging and re-enabling the Windows Pagefile.

If the Dev error 6178 clears, you might need to make the game run as administrator all the time. So, right-click the executable or shortcut again before choosing ‘Properties’ this time.
Next, head on to the Compatibility tab and Run this program as an administrator option.
Lastly, select Apply and click OK to save the changes.

Solution 2- Configure the Settings of your Game

To fix the error, you can also try configuring certain settings of the game to solve the problem. I believe that most users encounter this issue with a certain feature. Features like the NVIDIA Highlights enabled and Texture Resolution in a relatively compressed level.

Follow the steps to start the configuration

Startup the Settings of your Modern Warfare.
Navigate to the ‘options’ screen and switch to the ‘graphics’ tab.
Configure NVIDIA Highlights to ‘Disabled’ and head to the ‘Details & Textures’ section to set Texture Resolution as Normal.
