this is embarassing...same issue here started about a week ago. And for me is a big problem, because i usually play multiplayer online games and they drop to 33 fps. No chance other than close the game, reboot and praying it recognize back the graphic card. And no chance to know untill i start playing the game.
We spent a lot of money to have the best combination between hardware and software and than what happen? I'm so disappointed, really. And wondering if sell the book and buy other laptop is the right choise.
Please FIX IT! I saw that NVIDIA just released (GeForce Experience) a new driver. Hope it fixes the issue but i'm not confident in that
