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.
Compared to the stock clocked HD 5850 we see across the board a bump in performance. Compared to the GTX 470 the card does trail at 1920 x 1200 and lower with it pulling out a small win at 2560 x 1600 in the minimum department.
The good news is at 1920 x 1200 we're so far ahead of the 30 FPS minimum that it doesn't matter what card you use. As for 2560 x 1600, the HIS HD 5850 Turbo pulls out a win with a 5 FPS gap from the minimum.
