Hey guys, So I did the EFI firmware update and now my dynamic switching is broken. I cannot watch any video on the internet in fullscreen that has a 480p or lower resolution. Whenever I switch to fullscreen, the video becomes extremely choppy. This, of course, happens because the graphics card does not switch from Intel to nVidia. Anyone else have any similar issues or any idea how to fix them? I'm on a 17'' Core i7 Macbook Pro.
