Which display connections are driven by the NVIDIA high-performance GPU. Which displays and video are accelerated using the NVIDIA high-performance GPU. How do I know which programs, displays, and videos are using the NVIDIA high-performance GPU?Ĭlick the NVIDIA GPU Activity icon in the Windows notification area. See the Display Page Help Optimus Note for further information. On some notebooks or PCs, the NVIDIA Control Panel offers additional display configuration options not available through the standard Windows control panel. Other programs may need to run on a specific graphics processor if the program has compatibility issues with the other processor. The driver may override your selection if the program requires a specific graphics processor.įor example, some programs require the high-performance NVIDIA GPU for CUDA processing or advanced DirectX support not available with the integrated graphics. To allow the "Preferred Graphics Processor" settings to take effect, you must restart the program. When you modify the "Preferred Graphics Processor" setting, programs that are already running will continue to use the same graphics processor uninterrupted. If you experience this, select "Auto-select" or the default selection.
Your selection may cause some programs to not run correctly or may result in shorter battery life. Programs and videos that launch on external displays that are driven by the NVIDIA GPU will always use the NVIDIA GPU rather than the integrated graphics processor, regardless of the "preferred graphics processor" selection. Specify the graphics processor to use when you launch the program. Specify the graphics processor to use through the Manage 3D Settings "Preferred graphics processor" setting. When programs are run on displays connected to the integrated graphics, you can customise this selection in two ways: When you run a program, the NVIDIA driver automatically selects the appropriate graphics processor to use for the best performance - either the integrated graphics processor or the high-performance NVIDIA GPU. How do I specify which graphics processor my program uses? Note: Your PC manufacturer may provide a custom Windows power plan that prevents programs from using the high-performance NVIDIA processor. If there are no programs or displays using the NVIDIA GPU, then the window indicates that your PC is in power saving mode. When you click the NVIDIA GPU Activity icon in the notification area of the Windows taskbar, the window shows which programs and displays are using the NVIDIA GPU.
The technology optimises the balance between power savings and performance, and is available only with Windows 7 and later. NVIDIA ® power-saving GPU technology (NVIDIA ® Optimus™ technology for notebooks) automatically turns the high-performance NVIDIA GPU on to accelerate programs or displays.
