Can I Run Subnautica 2?
If your PC meets only the minimum specs, expect to lower visual settings for a playable experience. If your PC meets or exceeds the recommended specs, you should have more room for higher settings, but Early Access performance can still vary by area and patch.
PC Performance Expectations
Subnautica 2 is built on an improved engine relative to the original Subnautica. The underwater environments, creature animations and water rendering can be GPU-intensive, especially at higher detail settings. Players with mid-range hardware should expect to adjust settings like water quality, vegetation density and shadow resolution to maintain smooth framerates.
