In general, at least for my specs / resolution / framerate I would say the game actually runs a bit worse than it did.

They did some changes a few patches back that made the ocean look worse, and I started to get a lot more small frame drops. Think they may have added a thicker distance fog trying to improve performance but really made it worse trying to render it.

But it is early access so I know this kind of thing will change a lot over time.
