The NVIDIA 3D Vision process nvSCPAPISvr.exe is running automatically on the system if you have installed the driver, no matter if your hardware is 3D compatible or not. This means that you either need to disable the driver during setup (by selecting custom setup) or to stop the NVIDIA Stereoscopic 3D Driver Service from running if you have selected automatic installation. Regardless of that Most users won't have the hardware to make use of the feature. This updated driver version adds support for new projectors and desktop LCD monitors, support for HDMI 1.4 3D TV's when using 3DTV Play software, 3D vision game profiles for select games and performance improvements. The second addition is the inclusion of the 3D Vision Controller driver which adds support for NVIDIA's 3D Vision technology that requires a compatible graphics processing unit, specialized 3D glasses and displays or projectors. The preferences tab offers options to disable automatic update checks, change the frequency of updates from the default once per day setting to once an hour, week, month or during login, and to include beta updates in the checks. Here it is possible to manually check for updates and to change the preferences of the updating module. Users can change the frequency of update checks and other settings in the NVIDIA Update options, accessible via the System Tray icon. The process itself will run in the background all the time. It launches the daemonu.exe process and will make a single check per day for new stable drivers and display notifications to the user if a driver update has been released. The new component will be installed as a system service on Windows.
