Nvidia has released new beta drivers offering GeForce 400, 500 and 600 series owners up to 18% more performance depending on the title and settings. In a blog post, Nvidia published some of its own tests in which the GTX 680 saw a 17.6% boost over last month's 301.42 WHQL release in Batman: Arkham City, 12.4% in Dragon Age 2, 9.8% in S.T.A.L.K.E.R.: Call of Pripyat and 4% in Lost Planet 2 when running the games on high or max settings. A 5.8% to 15% bump was recorded with a second GTX 680 in SLI.
As a second example, Nvidia shared the GTX 560's results when shifting to the beta drivers, including 14% more performance in Arkham City, 6.7% in Lost Plane 2 and 5.5% in Dragon Age 2. When paired with another GTX 560, the combo delivers 11.9% more frames in Arkham City, 5.2% in Battlefield 3, 6.1% in Dragon Age 2, 4% in Lost Planet 2, 5.3% in S.T.A.L.K.E.R.: Call of Pripyat and 7.9% in The Witcher 2: Assassins of Kings. Nvidia's article provides more information about how each game was configured.
The beta release also fixes a bug in Shogun 2: Total War that reduced frame rates by up to 60%, another that caused intermittent vsync stuttering with GTX 600 series cards as well as a bug that prevented some overclocked cards from running at their higher clocks. Nvidia has also added or improved a handful of new SLI and 3D Vision profiles for games including Torchlight II, Tribes: Ascend, F1 2011, Planetside 2, Borderlands 2, Mass Effect 3, Max Payne 3, Street Fighter X Tekken, and The Walking Dead.

Meanwhile, Diablo III, L.A. Noire, Rayman Origins, and The Secret World have gained antialiasing support in the Nvidia Control Panel, and Star Wars: The Old Republic's ambient occlusion can be set in the Nvidia Control Panel. FXAA, Nvidia's antialiasing solution, has been disabled in Windows programs like Media Player and Movie Maker. Although FXAA has been well-received, its effects were being applied to Windows applications when set to run globally, making text difficult or impossible to read.
The Nvidia GeForce GTX 680 contains four GPCs with a total of eight SMXs, 1536 CUDA cores, eight geometry units, four raster units, 128 texture units, and 32 ROP units. The base clock is 1006MHz, the GTX 680 also carries 2GB of GDDR5 VRAM running at 6008MHz with a 256-bit interface providing 6.0Gb/s of throughput. Dual six-pin power connectors feed the card's TDP of 195W.
The Nvidia GeForce GTX 690 features 3,072 CUDA cores, 4GB of GDDR5 RAM at 6.0Gbps running on a 512-bit bus and a base clock of 915MHz, although it can be boosted to 1019MHz. Video output is provided by three dual-link DVI ports and a single Mini-DisplayPort 1.2 output. Power is provided by two 8-pin connectors using a new 10-phase heavy duty power supply which is connected to a ten layer two-ounce copper PCB.
The NVIDIA GeForce GTX 560 Ti 1GB boasts 384 CUDA cores, there are also 64 TAU (Texture Addressing Units) units. Breaking it down, we have 2 Graphics Processing Clusters, 8 Streaming Multiprocessors, 384 CUDA Cores, 64 Texture Units and 32 Raster Operations Units. The GeForce GTX 560 Ti is paired with 1024MB of GDDR5 memory clocked at 1002MHz (4008MHz DDR). Combine that with a memory interface of 256-bit and you get a peak theoretical bandwidth of 128GB/s.
