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.
At the lower resolutions we see the MSI HD 4890 is able to come out ahead. When we move to 2560 x 1600, though, the 2GB Sapphire offering is able to sneak ahead.
