I'm sorry if this has been solved and I just didn't find the thread but I'm having issues with MM 7 and 8 both giving me screen flickering every 5-10 seconds. Don't have the issue with MM6 mandate of heaven. Was there a solution to this?

I'm playing on a Windows 7 machine with 8gb ram, a GTX 670 and an i5 btw.

my win7 does the same thing,it could as simple as restarting game again or compatibility mode.I had a lot of trouble with Anno 1404 Venice,but simply restarting game seemed to fix the problem..
