Estimate per graphics card
No frame-rate estimate for this game
The official page does not name a specific graphics card for both the minimum and the recommended specs. Rather than an invented number, we give none. ORION does the maths on your own PC, with your card, processor and screen, then measures the real frame rate while you play.
