How to get the best frame rate in Subnautica: Below Zero
The publisher's minimum for Subnautica: Below Zero is Intel HD 530 or better with Intel Core i3 4XXX series / AMD Ryzen 3 2.6ghz+, and the recommended hardware is Nvidia 1050 Ti / AMD Radeon 570, 4GB VRAM. We treat the recommended hardware as the setup that holds about 60 fps at 1080p on High.
In our estimates a GeForce GTX 1050 Ti is about the weakest card that holds 60 fps on High at 1080p, a GeForce GTX 1650 does the same at 1440p, and a GeForce GTX 1070 at 4K. Cards below that can still play the game, at Medium or Low.
Open world and story games are limited by the graphics card in busy areas and by video memory in new locations. If you see stutter when you enter a new area, lower the texture setting a step. Turn on upscaling if the game offers it.
