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.
Looking at Far Cry 2 performance, you can see as we up the memory MHz which in turn has upped our CPU MHz, our minimum and average FPS improves. It's nothing major, but we see that the more MHz we get from our modules in turn lets us achieve more MHz from the CPU which offers us a bump in performance.
If you compare this to someone running the CPU at stock with 1333MHz DDR memory, the extra performance is extremely large.
