Published minimum specifications
The following values come from the current official Steam requirements, checked September 5, 2026.
| Component | Windows minimum | macOS minimum |

Steam does not supply a separate populated recommended-hardware tier in the reviewed listing. A heading labeled “Recommended” without component values is not a recommendation to invent your own GPU or processor.
What these numbers do not guarantee
A minimum specification is not a benchmark for a particular frame rate, resolution or large settlement. We have not measured performance on these machines. Compare every relevant component rather than using available storage as a proxy for whether the game will run well.
When advice conflicts
Use the current official table, then check the version attached to a performance report. An earlier search snapshot returned conflicting numbers even though a later page visit was corrected; this guide does not average old and current specifications together.
CanOpener is already issuing Early Access updates. Those notes identify the changing build context, but they do not replace the hardware table or prove a particular optimization result.
