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 1680 x 1050 we can see that the HD 5750 doesn't run into any problems breaking that 30 FPS minimum we want to see. At 1920 x 1200, though, the card does fall back a little, but a bit of a detail drop would get the numbers back up if you want to play at this resolution.
