Für alle mit schwarzem Rand, hier ne Anleitung, klappt bei mir.
Go to CCC - Desktop and Displays -> right click on the lower left screen, select configure, go to HDTV support, move down to the part where you create a custom resolution, select your "1080p60 standard" resolution, click add.
In the white screen that appears there are four red selectors with arrows in them. Click once on the lower selector and you will see the resolution changing to 1920X1076. CLick accept and the select apply. Please note that if you also select keep aspect ratio, it will also reduce the 1920 to 1912 pixels. I found it more preferable to leave it at 1920X1076.
Now from within Crysis, select this resoltion 1920X1076 instead of the 1920X1080. Not that you may have to scroll down a bit. There is a slider on the left, that some people miss. Now you will be able to play Crysis at full screen, 60hz. There is just one tiny blank on the top (in my config at least) which is 4 pixel tall, but it is not noticable at all.
This solution works for Crossfire configurations as well.
Also this new resolution can be used in all other games that have frequency problems.
