someone please help me, am using the ATI Mobility Radeon HD 4200 Series (Engineering Sample - WDDM v1.1) on an hp pavilion g7-11767dx. i quite recently install the windows 8 release preview on it, but the problem is that, when i also installed fifa 12 on it, there were big black lines on the pitch, very big line on the pitch, obstructing your view, at first i thought it was the game setup, until i installed other games and realize it was still the same. am using the catalyst for windows 7 on this pc, but wen i was formally using the windows 7 i wasn't experiencing such problems, someone please help me
