Recommended requirements
The Steam store page does not publish a separate recommended tier at launch — only the minimum table above. We'll add it here as soon as Cold Symmetry publishes one.
What the spec tells us
- 70 GB install is large — plan storage accordingly (UE5 asset streaming)
- 8 GB VRAM GPUs are the floor; expect settings tuning below that
- The mandatory SSD means HDD installs will hitch and fail to stream assets
These are the minimum specs only. If you're below them, expect launch-week performance issues to hit you hardest — see our known issues page for mitigations.
