What applications are supported with SLI technology?
SLI technology can be enabled for every gaming application, including both OpenGL and Direct3D gaming applications. SLI technology provides either 3D performance scaling using alternate frame rendering (AFR) or split-frame rendering (SFR) or increased visual quality using the SLI Antialiasing mode. In order to provide the optimal 'out-of-box' experience for its customers, NVIDIA has created an extensive set of optimized game profiles which enable SLI scaling automatically. The full list of these SLI-optimized games can be found here. For applications not found in this list, simply follow these quick instructions to set up a new game profile to enable SLI technology. Information about professional application support can be found here.


Why don't all games see performance increases?
Applications which tax the GPU will see tremendous performance improvements of up to 2x with SLI technology when using two graphics cards. Most of today's hottest games and as well as next-generation games fall into this category. However, some applications, typically older generation applications, are limited by factors other than the GPU's processing power.

The most common limitation is the CPU. If an application becomes CPU bound, no additional graphics power can improve performance. This situation is most common at low screen resolutions like 1024x768 with no additional functionality turned on. Turning on antialiasing and anisotropic filtering or switching to higher resolutions can often move the processing requirements back to the GPU.

For CPU-bound applications, NVIDIA offers a new SLI rendering mode called SLI Antialiasing. This rendering mode allows you to enable SLI8x, *SLI16x, or SLI32x (for quad SLI only) antialiasing and enhance the visual quality of any gaming application.

does not mean that there will be a toggle switch in setup options for dual video cards
