Hi,
i bought Wargame EE and i cannot play, because when i launch a mission, the screen begins to flash (black screen/desktop/black screen/desktop and so on).I can only play on ultra-low details. After i press ctrl+alt+delate, and display the list of running applications, i can see "Wargame - DirectX9", even though i changed the compability into windows 7! i want to run this game DirectX11. Does anybody know how to change DirectX permanently?

This has worked for others.

Open your steam folder and follow this path
Steam>>>>Steamapps>>>>Common>>>>WargameEE

Look for the WGEE ext icon{should be around 25,550kb}

Right click it an look for properties....then compatability.
Make sure its set to Win7


Also, if you can, post your DxDiag report.
