Mac compatibility
Can you play Subnautica 2 on a Mac?
Short answer: Likely to work, but not tested yet — Subnautica 2 requires DirectX 12, which Grapple runs through D3DMetal. Nothing extra to download; tell us how it goes.
What we know
Steam lists Subnautica 2 for Windows only. Both its minimum and recommended requirements call for DirectX 12.
Grapple includes Apple's D3DMetal, which handles DirectX 11 and 12, so a DirectX 12 game needs nothing extra from you. That's an expectation, not a result — we haven't tested it yet.
Grapple settings
Nothing verified yet. Where to start, based on its DirectX version (in the app, the same options are in the game's settings):
- DirectX 12 runs through D3DMetal, which comes with Grapple — a new install already uses it, and nothing needs downloading. See the Game Porting Toolkit guide.
- To see frame rates, turn on the Metal HUD:
