Recently, Unknown Worlds Entertainment released the final version of Subnautica: Below Zero. This is a survival game that is a continuation of the original Subnautica. The first game of 2018 was remembered by many thanks to the great atmosphere and the original setting, where we explored the alien underwater world. Below Zero sends us back to a familiar planet, but to a different part of it, where a random survivor will have to uncover new secrets.
Competently built plot turns the game into a fascinating exploration. Now underwater dives are diluted with longer aboveground stages. The surroundings have changed a little due to the fact that the events take place in cold latitudes. Therefore, we are expected to meet with new creatures and new dangers.
The game uses the Unity engine and runs in the DirectX 11 environment. There is a feeling that the game has improved the work with LOD and the range of drawing the underwater world. Other significant technical changes are not visually noticeable.
List of test participants:
All video cards were brought to the standard frequencies for their series, overclocking was not involved.
Full specifications are given in the table.

The test sequence consisted of a short dry run and a swim along a specific route at the starting location. Several repetitions to reduce the error. Measurements were made using MSI Afterburner. High graphics quality profile selected.
The graphs show 1% low, minimum fps, average fps.
Test results
Let’s start with a Full HD resolution of 1920×1080.
Even the old GeForce GTX 1060 and Radeon RX 580 cards perform well, although they can drop below 50 frames in difficult scenes. The new GeForce RTX 3060 is more than enough. The video memory load is less than 4 GB.
Top video cards are tested only in high resolutions.
As the load increases, the advantage of the Radeon RX 5700 XT over the GeForce RTX 3060 becomes more pronounced. The minimum difference between the GeForce RTX 3070 and the GeForce RTX 2080 Ti. At a higher level, the results are the Radeon RX 6800 and Radeon RX 6800 XT, which are second only to the GeForce RTX 3080 Ti.
At 4K resolution, the old flagship GeForce RTX 2080 Ti minimizes the gap to the Radeon RX 6800. These graphics cards can be called the minimum choice for this resolution. The GeForce RTX 3080 Ti outperforms the Radeon RX 6800 XT by 25-27%.
conclusions
To enjoy the underwater world in Subnautica: Below Zero at standard Full HD resolution, you do not need top-end graphics cards. The old GeForce GTX 1060 and Radeon RX 580 will cope with this task, but for complete comfort, more productive models are needed. The GeForce RTX 3060, Radeon RX 5700 XT, and increasingly powerful solutions handle 2560×1400 resolution. But at 4K, the game already presents a serious load, even the GeForce RTX 2080 TI with the Radeon RX 6800 is the minimum choice for high resolution. Comfortable performance at stable 60 frames and above in this mode will be provided by the GeForce RTX 3080 and GeForce RTX 3080 Ti. These graphics cards have a significant advantage over the Radeon RX 6800 XT.
