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.
The top four cards here perform all quite close to each other. The only card that shows us any real difference is from Palit and again that's thanks to the company choosing to overclock both the core and memory.
We're still a good chunk away from the 30 FPS minimum we want, a decent drop in detail or a lesser drop and a move back in resolution should fix the issue and bring us a lot closer to that 30 FPS minimum we want to see.
