@Paolla, iif you have the Nvidia GPU and the INtel integrated on your laptop please make sure that you run interface with Nvidia.
If you right click on your desktop background you can go into the control Panel from Nvidia
THere you need to go from the left tlist view to select “3DSttings/Manage 3D Settings”
THis shows you a page with 2 tabs (global Settings, Program Settings)
In Global settins tab, the first combo menu(Global presets) choose "Base Profile"
In the second combo box (Preferred graphics processor) select “High-performance NVIDIA processor”
Eventually reboot and make sure that the settings are the same after the reboot.
Also make sure you are currently on the latest driver version for nvidia
check that in the same nvidia control panle, low left corner click the “system Information” link
It shows you a new doialog box with that information, for me right now i m using Driver version 340.84 on my laptop and i m using a quadro k2100M
It would be probably different but close if you are using a geforce
