So in essence nothing has really changed. The problem is there are a few games (it seems like very few) that are hard coded to run at 60hz, and since Windows 7 is reporting 59hz instead of 60 it is causing the game to break, even though the refresh rate hasn't really changed.

that explains it i had DDC/CI off.
turned it on, and OS shows 59, and monitor still shows 60hz
haha, clueless folks making all this ruckus just because they don't understand DDC/CI and EDID.
