Mid Game Display Change Dirt 3 with HD 6770

[7racecar7]

Not sure if this is called flickering but I have 3 monitors running in eyefinity mode and the introductions and menu screens are running fine, but when i start to play the game the display setting starts changing, it basically cycles through a number of displays, sometimes it ends on just 3 duplicates on each screen other times it is a diffrent resolution, and sometimes it just keeps looping.

Any ideas where to start here? updated drivers from CCC have most current version, running windows 7 64, quad cpu, 4 GIG memory, 650 power
