From there, disable light shafts and set shadow cascades to 2. If this isn’t enough, you can access additional settings by hitting Tab and then F3 in-game.

Motion blur and FXAA should always be turned off, as they don’t improve visual quality particularly and cause unpleasant blur.

The game has excellent lighting effects, but turning off bloom might also give you the boost in performance that you’re after.Same goes for screen space reflections and ambient occlusion. Depth of Field, on the other hand, can have a big impact on performance, so make sure to turn that off if you’re having trouble.Surprisingly, neither does Water Quality, as it principally affects the appearance and animation of the ocean surface (which you won’t be seeing all that often).Dithering is a process to help your GPU render specific colours, though it doesn’t seem to have too much effect on performance.This generally downgrades texture and rendering quality, which can help a lot. To begin with, turn the Game Quality down.Subnautica’s graphics options aren’t the most extensive, but if you’re having trouble getting a stable frame rate there’s certainly things to be tweaked.
