Some players reported thatupdating the graphics driver could improve the performance of Subnautica and stop the crash. So if you don’t know whether you’re using the latest GPU driver, have a check or just go right ahead and do an update.

You can update manually, by visiting the manufacturer’s website (NVIDIA /AMD ), searching your model and downloading the latest correct driver installer. But if you don’t have the time, patience or computer skills to do it manually, you can do it automatically withDriver Easy .

3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.(This requires the Pro version – you’ll be prompted to upgrade when you click Update All. If you don’t want to pay for the Pro version, you can still download and install all the drivers you need with the free version; you just have to download them one at a time, and manually install them, the normal Windows way.)
   

The Pro version of Driver Easy comes with full technical support . If you need assistance, please contact Driver Easy’s support team at [email protected] .

After updating your graphics driver, restart your PC and check if Subnautica: Below Zero crashes again.

Fix 5: Stop overclocking

Overclocking is not something new in 2021, basically every motherboard and graphics card has this gimmick. But when you’re enjoying this zero-cost performance booster, beware of the side effect of making your system unstable. So if you’re using overclocking software, such asMSI Afterburner andIntel Extreme Tuning Utility (Intel XTU), or you’re using a BIOS setting to overclock, disable it and test the gameplay again.

You might also need to disable hardware monitors like AIDA64 and NVIDIA GeForce Experience.
