Pixel shaders are just everywhere in F.E.A.R. , but they are not so complex as to reveal fully the potential of the RADEON X1000 architecture, at least not unless full-screen antialiasing is turned on. The Sapphire RADEON X1800 XL is slower than the GeForce 7800 GT in the “pure speed” mode, although the gap is actually negligible in 1600x1200. At the “eye candy” settings, however, the Sapphire beats the GeForce 7800 GTX in two out of three resolutions! Well, there is actually only one playable resolution, 1024x768, because the speed of the Sapphire card is below the empirically comfortable frame rate of 50-60fps in higher resolutions of the “eye candy” mode.
