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.
With the extra grunt we're not at the 30 FPS minimum we need to see. We should be able to gain those last few FPS at 1680 x 1050 with a detail drop, however.
