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.
Far Cry 2 sees some significant gains at the higher resolution. While it isn't doubled, the 25 FPS increase does translate to around a 40% increase which is nothing to be shy of.
