tried and failed
ive done a bit of research on this problem and what ive found is this problem has been occurring since june with many other win7 64 users, and they have not done anything about it.
im gonna keep my eyes open on this but the only workaround i have right now is to boot up in xp and it plays just fine (not only that but in xp only one of my video cards is being used and the frame rates are better than they were in 7 using quad sli)
