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.
Already we had good numbers from the HD 6850 which managed to give us playable numbers at all resolutions. In Crossfire we're able to almost double those numbers and performance between the GTX 460 OC SLI and HD 6850 CF setup is very close. The latter setup would pull the overall win as it only falls behind once and that's by only a single FPS.
