Subnautica

What works

Gameplay during about 2 hours from beginning. All vehicles tested, most tools tested.

Gameplay works just fine, all tools tested work, framerates are low, but stable.

Audio works fine without issues.

What does not

DX11 mode (standard) is utterly broken. You get sub 5 FPS and many, many items are completely transparent (invisible). Examples include the escape pod, almost every single tool, Cyclops bay doors etc.

With OpenGL framerate is much lower than on Windows. In the orders of 30-40 FPS, whereas it's 60+ on Windows.

It also has some pretty severe z-fighting inside vehicles and inside habitats leading to flicker on walls.

Workarounds

It must be run with -force-opengl to see everything and have decent framerates.

What was not tested

Complete playthrough, most of the alien stuff was not used or visited.

Hardware tested

Graphics:

• GPU: Nvidia
• Driver: proprietary

Additional Comments

Major problems involve low performance, persistant z-fighting on walls and inability to use high quality water effects.
