Odd.. I have a 7850 (Sapphire brand) and havent had this, or any issues at all for that matter. A lot of older games tend a hard time keeping up with the new series' of graphics card, thus making graphical compatibility a little wonky. It could be that, or your CCC, or a combination.
It is quite odd indeed. It's a HIS brand btw. I didn't have this issue with my 5670 neither, and the game pictured is DotA 2 a game not even released yet. I queried whether or not that it was simply the max shadow (as it is a beta) but many of my friends replied that there's are much smoother.
You might want to try booting into safe mode, getting rid of all of your video drivers with Driver Sweeper (it's a free program that you can download. Just google it.), reboot, and then install the latest drivers for your graphics card. That might help, but no guarantees.
