A new driver from NVIDIA was just released, it's as beta though. The drivers have some very cool new options for PhysX, and multi-monitor GPU gaming. Obviously this driver has new Far Cry 2 optimizations harbored in them as well.

Beta driver for GeForce 200-series, 9-series, and 8800-series desktop GPUs.

Recommended for the best experience on Far Cry 2:

“Since we first began working on Far Cry 2 in early 2005, we have used GeForce GPU’s to develop the game and worked closely with NVIDIA’s excellent engineers. While Far Cry 2 represents an outstanding PC gaming experience for a wide range of systems, GeForce users can expect to enjoy the game quite literally ‘The Way It Was Meant To Be Played’.” - Louis-Pierre Pharand, Ubisoft, Far Cry 2 Producer
