Deep Rock Galactic PC faces errors and problems such as startup failure, black screen, X3DAudio1_7.dll not found, XAPOFX1_5.dll missing, fatal error and others.

Here, I have compiled a list of errors encountered by players, as well as their fixes and workarounds.

Deep Rock Galactic game crash

Deep Rock Galactic finally got out of early access and is fully ready for new players. However, the PC version of the game still faces such problems and bugs as LowLevelFatalError, Unhandled Exception, lags and brakes, No Audio and others.

Below are the errors and problems faced by players, as well as their corrections and workarounds.

Black screen – how to fix it.

Black screen is a common problem among computer video games, and Deep Rock Galactic is no exception. Players report that when they launch a game, they hear the sound and mouse cursor moving on options, but all they see is a black screen.

Launch Deep Rock Galactic, and when the black screen appears, press “Alt + Enter”. It will go into window mode and will start showing.

Change the resolution according to the screen resolution, and you will be able to start the game in full-screen mode. Also, starting the game in Windowed mode also causes a black screen problem, so start the game in normal full screen mode and the black screen problem will be solved.

Another reason why the black screen appears when you run Deep Rock Galactic are the drivers of GPUs. Just roll back the old driver and the problem will be fixed.

X3DAudio1_7.dll, XAPOFX1_5.dll missing, fix fatal 0x80070643 error.

According to Deep Rock Galactic players, when they launch the game, they receive a message that certain DLL files are missing or not found, or 0x80070643 Fatal Error. These missing DLL files include:


All you have to do is download and install the latest DirectX files, and the errors will be corrected.

Unreal Engine Crash

Some players report that they see Unreal Engine Crash when running Deep Rock Galactic. This error is related to Duet Display, a third-party software that causes Unreal Engine to crash. Simply uninstall the software or any third party software that may interfere with the game and the failure of Unreal Engine will be fixed.

Fix LowLevelFatalError

Some players report that they get LowLevelFatalError when the game flies out on their laptops. The following is a complete error.

LowLevelFatalError [File:C:\P4\UnrealEngine\Main4-19\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 233].
Result failed

If you have been playing the game for several hours before this error occurred, just restart the system and the LowLevelFatalError error will be fixed.

Otherwise, your laptop will most likely run the game on the built-in GPU rather than on the dedicated one.

For users of Nvidia GPUs, open the Nvidia Control Panel> 3D Control Settings> Program Settings> select the game.

On step 1, select the option Unintegrated GPU, apply the changes and start the game, and the error is now fixed.

For AMD GPU users, open Device Manager and turn off the built-in GPU option under the display adapters.

The game doesn’t start, failure at startup.

According to the players, Deep Rock Galactic falls immediately at startup or does not start at all. There are many reasons for these problems, and here’s how to fix them.

Lack of administrative rights is one of the reasons why the game crashes at startup. Make sure that you use a Windows account with administrative rights.

If so, right-click on the exe game> Properties> Compatibility tab> check the “Run this program as administrator” box. Apply the change, and the problem will be fixed.

Another reason Deep Rock Galactic failed to start is to use third-party software such as MSI Afterburner or GeForce Experience.

Disable any third-party monitoring software that you are using and the game will not hang up at startup.

If the above does not solve the problem, the culprit may be your antivirus or Windows Protector. They may have mistakenly recognized an exe game as a Trojan. Either disable the antivirus, or exclude the game folder from the antivirus, and the failure at startup will no longer be a problem.

Fix for an unprocessed exception

According to some players, when they run Deep Rock Galactic, they get the following error.

Unprocessed exception


This problem is related to your GPU driver. Do a complete uninstallation of the GPU driver and reinstall it, be sure to perform a clean install. This will fix the Unhandled Exception bug.

No sound – how to fix it.

Some players report that they do not get any sound when playing Deep Rock Galactic. One of the reasons for lack of sound or lack of sound is the game’s own equalizer. Simply mute it, and the sound will start to work fine.

Correct lags and brakes
According to the players of Deep Rock Galactic PC, they experience microtremor while FPS is stable. To fix this, turn off v.sync in the game.

Open Nvidia Control Panel>Control 3D Settings>Program Settings>Choose Game>Set Vertical Sync to On. Apply the changes, start the game, and the stuttering will disappear.

If the game still stutters, follow the steps described above, but set the parameter “Vertical Synchronization” to “Fast”.

The Fast option simulates G.sync because it allows the GPU to display as many frames as it can, but can only display as many frames as the monitor supports.

This means that if a game plays 80 frames per second and the display is displayed at 60 Hz, then the game will display only 60 frames per second and the remaining frames will be discarded.

To avoid this, lock the game’s FPS. You can do this in Nvidia Control Panel> 3D Control Settings> Program Settings> Select Game> Maximum FPS Limit. This will not only eliminate lags and brakes in the game, but also relieve the GPU from rendering unnecessary frames.

These are all options for fixing Deep Rock Galactic, such as black screen at startup, Fatal Error, LowLevelFatalError, lags and brakes, startup failure and much more.
