Im having a problem with CF(crossfire) everytime I play it freezes after a seconds and I need to restart my com again. I cant play CF at my computer. I suspected the system I am using its Windows 7 so I tried the compatibility mode and run CF to previous system wich is Windows XP SP3 and nothing happen. Now I am suspecting the version of DirectX I am using. Its DX11. My Vcard is GeForce FX 5500 with DX9 but window 7 uses DX11. is that a problem? can CF be played by DX11? or is there other problem I have?
