That's bad, I have not yet gone to the aurora yet, I am currently experiencing stuttering and frame rate drop every time I'm surfacing above with all the splashes effects going on. I hope they patched it soon.
I hope they add weather on subnautica on a later date which is in line with the story and atmosphere on the planet, not just for below zero expansion. It will be great for more immersion.
I'm in saudi arabia, good thing I have u.s account, so i just downloaded the digital version. I hope they patch it soon with the issue with frame rate when going above surface.The game is awesome overall! ps4 pro here.
