Subnautica game crashes on startup
Subnautica is a pretty demanding game that not every computer can run. It is quite another matter when the characteristics of the computer allow you to run the game, and it is constantly “getting good”. Quite often, after launching Subnautica on a PC, the initial boot screen appears and everything ends there. After the screen with the version of the game appears, it crashes to the desktop.
The traditional solution – updating the driver does not work in this case, because the players have the current version of Windows and drivers. One interesting feature of the problem is that if you run the Task Manager while starting Subnautica, only the huge load on the video card is shown. As if the rest of the system resources (processor, RAM and disk) are not at all involved. After closing the window with the game, you have to manually stop the process, otherwise it continues to pull the video memory.

What could be the reason?
Possible primary sources of the problem:
- Too many saves inside the game. This leads to the consumption of a significant amount of RAM and HDD space.
- There is not enough free RAM. The computer may meet the minimum requirements, but there are many tasks running on it. If the lack of RAM is caused by other applications, it is enough to close them. Another option is to increase the paging file size. When the RAM runs out, the system will start using the hard disk memory. The only drawback of this method is that HDD memory is much slower than RAM. During a heavy load on the system, the game may freeze, but it does not throw it to the initial screen.
How do I fix the problem?
Based on user feedback and support responses, we have identified several effective fixes for the crash.
Roll back video driver
The bug is known to appear more often among owners of Radeon video cards. The reason is a bug that appeared in driver version 18.5.1. In the next beta version, the fix was also not followed, so it is better to return the video driver to the previous stable version. Usually the game starts working fine with driver 18.4.1. The required video driver can be found on the manufacturer’s official website, but it’s better to just roll back the changes.
How to rollback for NVidia and Radeon video cards:
- Make a PCM on the “Start” button, from the list that appears, select the “Device Manager” item.
- In the “Display adapters” section, double-click on the primary video card.
- On the “Driver” tab, click on the “Roll back driver” button.
- Indicate the reason for the rollback and start the procedure with the “Yes” button.
If the video driver is found to be unsuitable, you must manually download the previous stable version and install it on the system.
Turning off the integrated graphics card
Gaming laptops always have 2 video cards: integrated and discrete. The first is used to perform simple tasks. It doesn’t have high performance, but it consumes battery power much more economically.
The discrete card is designed for games, graphics editors, and other applications that require a lot of system resources. For Subnautica to work properly, you must manually tell the system to use a discrete card to run this game.
How to setup:
- Right click on the desktop and select “NVidia Control Panel” or similar for Radeon.
- Go to the section “Manage 3D parameters”.
- Click on the “Software Settings” tab.
- In the first paragraph, you need to specify the application for which the settings are changed.
- In the second step, “Select your preferred graphics processor …”, you must install the discrete video adapter.
- Apply changes, restart your computer.
Paging file extension
This method will help prevent the game from critical during peak times, but lags may occur instead. It is best to install an additional RAM card. It also happens that the game simply checks the amount of free memory and blocks its further work. Artificially increasing the amount of memory helps to completely get rid of problems with the game.
Algorithm of actions:
- Click RMB on “This computer” (the shortcut is on the desktop or in the “Start” menu) and select “Properties”.
- Click on the item “Additional system parameters”.
- In the “Performance” column, click on the “Parameters” button.
- Go to the “Advanced” tab and in the “Virtual memory” section click on “Change”.
- Unselect “Automatically select volume …” and set the item “Specify size”.
- Set the amount in megabytes equal to or greater than the amount of installed RAM.
Cleaning up useless saves
If the problem appeared due to the accumulation of saves, they can be very easily deleted.
- Open the game folder and follow the path Subnautica SNAppData SavedGames .
- Each save is located inside a separate directory. It remains only to select unnecessary saves and press the Del button on the keyboard.
All of the above should be enough for Subnautica to start working properly. This is usually the case.
