You can select which display to use as the multi-GPU focus display (the display to which you want to apply full SLI acceleration for full-screen applications). Windows Vista or later, and GeForce 8+ series GPUs If none of the displays in the multi-GPU group are the primary display, then the driver will select which display to use to view multi-GPU accelerated games. The GPU connected to this display will function as the "primary" GPU, all others will function as slaves to the primary GPU. Use the Set up multiple displays page to select which multi-GPU display to use as the primary display. You can select which display to use to view your game. If you have more than one display connected and multi-GPU mode is enabled, NOTE: If you dedicated a GPU to PhysX, the setting could be removed if you changed the multi-GPU configuration. The multi-GPU bar points to the GPUs that will work together to increase rendering performance. The GPU configuration visualizer shows the pending multi-GPU configuration as well as the display connections and enabled state of the displays.
If possible, multi-GPU rendering may still be enabled.ĭisable multi-GPU mode to disable multi-GPU rendering, for example, if you encounter compatibility issues with your 3D program. Maximize 3D performance to enable multi-GPU rendering where possible for maximum 3D performance.Īctivate all displays to enable all available displays. If there is no pointer, then the CPU has been selected for PhysX processing. The PhysX cloud indicates that all the active displays benefit from PhysX, and points to the GPU that will be used for PhysX processing. The GPU configuration visualizer shows the pending PhysX configuration as well as the display connections and enabled state of the displays. If you want to use your selected GPU only for PhysX and not for multi-GPU rendering, click the Dedicate to PhysX check box.
In the PhysX settings section, click the Processor list and then select the NVIDIA GPU to use for PhysX acceleration.Ĭhoosing "auto-select" lets the NVIDIA driver use the best processor for PhysX. To use PhysX GPU acceleration on multi-GPU systemsįrom the NVIDIA Control Panel navigation tree pane, under 3D Settings, select Set multi-GPU and PhysX configuration to open the associated page. Note: To use this procedure, your system must be PhysX-capable and have more than one GPU capable of running in multi-GPU mode.
