I've had crossfire (Dual HD7700's overclocked to 1100/1400) for about a month now, the whole time ive been using windows 8 but after reinstalling the OS due to a hard drive change i've got a new bug where any game that is running in windows 7 compatibility mode will cause crossfire to forget to enable when i run them (gpu load is 0% and core speed goes to idle for the second card in msi afterburner OSD and performance drops down to single card level)

Anyone heard of this problem or knows what i could do to fix it? ive googled around everywhere and cant even seem to find anyone else talking about it frown.gif
