Well the new nvidia driver, with shiny evolve fixes and optimizations is out, version 347.52.
Of course, checking for updates and installing through GeForce Experience seems to completely break GE. GG, nVidia.
If you need the update really badly (SLI support, for example), I recommend installing directly from nVidia, I’ve been told that will work fine (I didn’t try yet, it’s bedtime for me).
Hope they solve this quickly, if they can get something together by Wednesday, I won’t even notice.
