Installation went smoothly and even updated latest drivers (320) After doing all this, when I tried to find out the number of cores and memory stats using the sample code (DeviceQuery) provided in the toolkit the program says no cuda enabled device detected So I was wondering if it has something to do with NEW Optimus technology or any. Nvidia Optimus is a computer GPU switching technology created by Nvidia which, depending on the resource load generated by client software applications, will seamlessly switch between two graphics adapters within a computer system in order to provide either maximum performance or minimum power draw from the system's graphics rendering hardware.
