Far Cry 5 uses an upgraded version of the Dunia Engine used for Far Cry 4. Playing at 1080p, locked 60 frames per second on Ultra is possible with a GeForce GTX 1060 or Radeon RX 580, along with 8GB RAM and a decent quad-core processor. The system requirements are higher than Far Cry 4, but a fairly low-end gaming PC should be capable of running FC5 at Low graphics settings. Anyone with a decently clocked quad-core CPU will probably find themselves bottlenecked by their GPU.
Set in remote Montana, the themes of Far Cry 5 appear to revolve around religious extremism and right wing supremacists. Ubisoft certainly isn’t pulling any punches with this one, and three years ago when development started I doubt they could have anticipated the world they would be launching their game in.
