I have an Nvidia geforce 820m with a 376.54 driver version in an acer laptop but every time I open a 3d game it is flickering so much that it is unplayable also the preview on the control panel is flickering so much. I don't know if this affects but I also have an intel hd graphic card. I tryed updating my drivers but it did not work. Also when I disactivate the Nvidia GPU (and only use the intel) everything is working properly. Any help will be welcome thank you.
This is a preview from my Nvidia control panel :
