The newest driver release by NVIDIA brings higher frame rates, fixes for game issues (most notably the corruption in BF3), and new profiles for recent, or upcoming game releases. Take a look below at the benchmarks to get an idea of the improvement in performance the new 295.73 driver brings.
"In the scene tested GTX 560 performance increased by an amazing 44.5%, allowing the mid-range card to make full use of Skyrim’s Ultra graphics options (285.62’s 27.6 frames per second rendered Ultra unplayable in indoor locations). In the other results, GTX 560 SLI performance is up 44.1%, GTX 580 performance by 36%, and GTX 580 SLI performance by 17.3%."
"Outdoor performance tends to be CPU bound on higher end configs, though on the GTX 560 we did register a 16.2% improvement."
"At 1920x1080 SLI frame rates increased by 91.63% on the GTX 560, and 90% on the GTX 570. At 2560x1440, SLI frame rates increased by an astonishing 100.00% on the GTX 560, and 95.04% on the GTX 570."
As you can see, MW3 benefits from NVIDIA's Ambient Occlusion.
