Hi all,i have just built a new pc,a Z68 platform with a Sapphire 7950 OC Edtion. Now i have had two games,Dirt 2 and F1 2011 revert to windowed mode as i am playing the games. My native resolution is 1900x1200,i play with vsync on as i suffer screan tear. I have gone into properties and selected "Run game maximized" but i still have the taskbar at the bottom and a bar at the top of the screen while i am playing. I have clicked the maximize tab in the top right hand corner but nothing happens. If anyone can shed any light on why my pc is doing this,it would be greatly appriciated.
