Talking about Performance

Posted by Hugh 1 week ago

Performance, frame rate, FPS – When a game does not run fast enough, it’s hard to have fun. Subnautica doesn’t run fast enough right now, on either Steam or Xbox One. We’d like to update you on three things we are doing to improve performance on both platforms.

Calling for Backup

We’ve hired new programmers to work on Subnautica. Adding more people to a project is tricky, and can sometimes even slow down development. Right now, we are confident that more programmers specifically targeting performance will help us improve frame rates.

Look out for David – He’s chewing on frames and sending messages in our chat with headlines like “Just pushed a big chunk of optimization work to

We do not have the manpower to improve mod support, but we can save you some time reverse engineering our files. So here is how our terrain data works under the hood. Definitely ping me on Twitter or post on our forums, if you managed to build something cool with this information!

Terrain Data

Subnautica uses an isosurface polygonization algorithm called Dual Contouring to create terrain surface meshes from voxel data. The voxel data is stored in batches, each covering a cubic volume measuring 160 m on a side. Each batch is subdivided …

They say good things come to those who wait. I don’t know who they are, but they have clearly never had to wait this long for a Subnautica Xbox One update. We know it, you know it: It’s taking too long, and we are way overdue to push an update.

They also say that good things come in threes. That, we can agree with. It now looks like Xbox One will receive a three-in-one update. Subnautica on Steam is building up to an update right now: We may merge that work into Xbox One.

Silent Running, Voice of the Deep, and “the third update” would roll into your Xbox’s all at once. As usual, we can’t guarantee anything, or pick …
