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.
Up to 1920 x 120 the HD 4890 from HIS runs like an absolute charm with it beating out the GTX 260. Moving to 2560 x 1600, though, we see the card does begin to fall back a bit.
