Subnautica Below Zero Crash, 0xc0000005, And Fixes
Subnautica Below Zero takes players back to planet 4546B from the original game to face new challenges and find the truth. The game has finally come out of Early Access and gamers are loving it. While the game is optimized but, PC players are reporting errors and issues with Subnautica Below Zero like in-game crash, game crashing when loading save, Access Violation (0xc0000005), crash at startup, stuttering, and more.
The following are the errors and issues that PC players are experiencing along with their fixes and workarounds.
Game Crashing While Loading Save Fix
PC players are reporting that Subnautica Below Zero is crashing on PC when they try to load their save. Fix for this Subnautica Below Zero crash is very simple. Go to Steam’s install folder. If you chose the default installation directory while installing Steam, then follow the directory path below.
C:\Program Files (x86)\Steam\steamapps\common\SubnauticaZero\SNAppData\SavedGames
In the SavedGames folder, delete the “autocloud.vdf” file. Launch Subnautica Below Zero and load your save. The game will load without crashing.
Crackling Audio, Audio Stuttering Fix
PC Players are reporting that the audio in Subnautica Below Zero crackles or stutters, especially, when predators attack. Audio stuttering might be occurring due to vertical sync. Players can either disable v.sync or if they have an Nvidia GPU, at least GTX 10 series GPU, then open Nvidia Control Panel > Manage 3D Settings > Program Settings > select Subnautica Below Zero. Scroll down to “Vertical Sync” and select “Fast”. Apply this setting and the audio stuttering issue will be fixed.
As for the audio crackling, open Windows Settings > System > Sound > click Sound Control Panel > a new window will open. Select your active audio output device > Properties > Advanced tab. There will be multiple sample rate options. This is a bit of trial and error. Either lowering the sample rate or increasing it will fix the crackling audio issue with Subnautica Below Zero.
Game Not Starting, Crash At Startup Fix
Subnautica Below Zero PC players are reporting that the game is crashing at launch. There are multiple reasons behind it and here is how to fix it.
First, make sure you are using a 64-Bit operating system as the game doesn’t support 32-Bit OS. Also, give the game admin rights. Right-click Subnautica Below Zero’s exe > Properties > Compatibility tab > check “Run this program as administrator” and hit apply. This will fix the crash at launch issue.
Right-click Subnautica Below Zero in Steam > Manage > Browse Local Files. Launch the game directly from the exe and players might encounter an error similar to “vcruntime140_1.dll or MSVCP140.dll Was Not Found”. To fix the error, players need to install the latest Microsoft Visual C++ Redistributables both x64 and x86 versions. This will fix the crash at launch issue.
UnityPlayer.dll Caused Access Violation (0xc0000005) Fix
Subnautica Below Zero PC players are reporting that they are experiencing the Access Violation (0xc0000005) error and are unable to play the game. The error might be occurring due to your anti-virus/Windows Security. The anti-virus could be blocking important game files and causing the crash. Disable real-time protection or exclude Subnautica Below Zero’s install folder from it. After that, verify the game and files and the issue will be fixed.
If the Access Violation (0xc0000005) error continues to bother you. Open command prompt (CMD) and run it as administrator. Type “sfc /scannow” and press enter. Let the scan complete and after that, the error 0xc0000005 will be fixed.
For some players, Subnautica Below Zero is crashing while playing and here is how to fix this issue. One reason behind this in-game crash could be the use of third-party tools and software like MSI Afterburner, RGB Software, and more. Disable any third-party software you have installed and also disable Steam overlay and Geforce Experience overlay. The game will stop crashing after this.
In case the game continues to crash, update your GPU drivers and do a clean installation. If still Subnautica Below Zero is crashing, your GPU might the culprit. Use MSI Afterburner to reduce the GPU clock to default if it’s overclocked, even factory overclocked. Do the same if the GPU is old and reduce the GPU clock by 100 MHz. However, if you don’t want to mess with the GPU clock, then cap the game at 30 FPS. Open Nvidia Control Panel > Manage 3D Settings > Program Settings > select Subnautica Below Zero. Turn on ‘Max FPS Limit’ and set the value to 30. The game will be locked at 30 FPS, reducing CPU and GPU load. Subnautica Below Zero won’t crash anymore.
Low FPS, Stuttering Fix
Performance issues are quite common among PC video games like Low FPS, stuttering, and random FPS drops. Subnautica Below Zero is no exception and here is how to fix these performance issues and stuttering.
First, install the latest GPU driver and do a clean installation. Also, make sure there is no background process using too much GPU, CPU, or HDD.
Open Nvidia Control Panel > Manage 3D Settings > Program Settings > select Subnautica Below Zero and make the following changes.
Anti-aliasing-FXAA – “Off”
Anti-aliasing-Gamma Correction – “Off”
CUDA GPUs – “All”
Low Latency Mode – Ultra (if locked at 30 FPS, otherwise, player choice)
Set Power Management to “Prefer Maximum Performance”
Shader Cache – “On” only if you are using an HDD. Don’t need to enable it for an SSD.
Set Texture filtering – Quality to “High Performance”
Triple Buffering – “Off”
Set Vertical Sync to “Use the 3D application setting”
After applying these settings, players will see a noticeable improvement in performance.
