Hello,
anyone else have the same problem that Crysis 3 changes the gamma of Windows 7, even if I have closed Crysis?
The gamma values ??of Windows are still the same, but after the closing of Crysis, it is a lot brighter than normal. I must restart Windows 7 to look like the normal Settings.

Win 7 64bit
Nvidia GTX-560Ti
latest Nvidia drivers

I noticed it was doing this for me as well last night, so your not alone. It's not a huge issue or anything but it certainly can get annoying can't it? Hopefully it will be addressed in the first patch.
