I've been playing Subnautica on Linux Mint and I've noticed an issue where the game lags more and more the more I build. Building generally causes slight lag to the game, however the amount of lag building has caused me is worse than on Windows.

It should be slight lag and only be an issue if you build a ton of unreasonably sized bases. However after building even one regular size base, I'll drop from 60+ to like 25 FPS. And building a second tiny base as an outpost? Down to like 15 FPS. Even with graphics settings super low.

Has anyone else experienced this or have any suggestions to fix this? I asked on r/Subnautica but nobody was able to help as we figured it was a Linux-specific issue.

Here's my PC specs, to show they're not the issue:

• Linux Mint 20.3 (Cinnamon)
• AMD Ryzen 7 3700X
• Nvidia GeForce RTX 2070 Super
• X570 I Aorus Pro
• 2x16 GB Corsair Vengeance Pro DDR4
• Crucial P1 1TB M.2-2280 NVME SSD
