World in Conflict v1.05
The Geforce 6800 GT and 7950 GT only run with DirectX 9 effects. Optically, the sunrays breaking through the clouds are missing, and the more simple HDR rendering shows normal blending effects.
The Geforce 6800 GT and the Q6600 are a bad combination: at high resolutions with antialiasing, the frame rate drops to below 1 fps which, freezes both the game and Vista completely. If the Geforce 7, 8 and 9 are used in conjunction with a weaker CPU such as the E2160, the graphics performance is halved. Respectable results with the E6750 are achieved at 2.67 GHz; if the Q6600 is overclocked to 3.2 GHz, the Geforce 8 and 9 still have a little left in reserve.
