The SLI multi-GPU dialog window can be opened by clicking on the Advanced button of the Settings tab of the Display Properties window:

If you enable the multi-GPU mode, the driver will require that you reboot the computer. Agree to this proposal and after the reboot enter the driver settings window again and click the Show Advanced Settings option on the Performance & Quality Settings tab:

The SLI Rendering Mode radio button determines the behavior of the graphics card pair in case a game is launched which is missing in the database of the ForceWare driver. By default the button is set to “Single-GPU rendering”, so only one graphics card will be used if such an unknown game is started. If “Multi-GPU rendering” is selected, the system will try to use the multi-GPU mode even in unfamiliar applications. In this case you can get a performance boost or you can have image artifacts and/or system instability. It’s up to you which mode to use. Having chosen a mode, click the Apply button. The system is ready to run your games.

In the next section you will learn the configuration of our test platforms, the driver settings and the list of games we used for benchmarking.
