Doom3: High Quality
In Doom3, we used Demo1 which comes with the game set to High Quality settings and with all other features activated (except FSAA). 8x anisotropic filtering is activated by default in this setting.
In Doom3, the 6600 GT is hot on the heels of the X800XT. Its performance is impressive compared to that of the 5950 Ultra. Even when the 6600 GT is underclocked to emulate the vanilla 6600, it still manages to beat the previous flagship model - calling this remarkable would be quite the understatement
