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 paints a similar picture to what we've seen all along. At up to 1920 x 1200 the three cards perform quite similar, especially in the event of the GTX 275 and GTX 260. Climbing to 2560 x 1600 does separate the cards a bit more, though.
