Far Cry 2
The Dunia Engine was built specifically for Far Cry 2 by the award-winning Ubisoft Montreal development team. It delivers the most realistic destructible environments, amazing special effects such as dynamic fire propagation and storm effects, real-time night-and-day cycle, dynamic music system, non-scripted enemy A.I. and so much more.
Here we see the HD 5850 CrossFire falls only second to the HD 5870 CrossFire setup. As for performance gains to the single setup, we see some massive gains with Far Cry 2 really making excellent use of CrossFire technology.
