Quick answers

Running D on PC

Can my PC run D?
Compare your CPU, GPU and RAM against the minimum column below. If your parts match or beat every minimum row, the game will launch — though you may need to lower settings. Matching the recommended column is what gets you 60fps at 1080p.
How much storage does D need?
1 GB available space
What is the difference between minimum and recommended specs?
Minimum means the game starts and is playable, usually at 30fps on low settings at 1080p. Recommended is the developer's target for a smooth 60fps experience at high settings.
