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.
Being under 30 FPS, but still close, means that the extra FPS we're able to get brings us even closer to the minimum we want to reach at 1920 x 1200. In all seriousness, a minimum of 28.5 FPS is really going to be fine for the most part. Move down to high or even lower and the whole gaming experience will be even smoother.
