After upgrading my MSI CX640 16Y1 from W7 to W 10, device manager under display adapter shows both the Intel HD 3000 and the Nvidia GT 520 M as enabled. I can access the Nvidia Control Panel, and thru G force experience update the drivers. However there is a icon “Nvidia GPU Activity” in the noticification area saying “There are no applications running on ths GPU”. So I imagine the graphics are provided by the i3 CPU. An inferior configuration for performance. In the previous W 7 OS there was only one entry in display devices; Nvidia, not two as present. I have checked bios and there is no entry regarding graphics. So has anyone come accross a solution to this issue ?
