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.
Across the board we see a nice little bump in performance. The best gains seem to be seen at 1920 x 1200. At 2560 x 1600 we can see that extra bus-width and ROPs help push our performance to that 30 FPS minimum we need.
