First Person 3D Shooters

Call of Duty: United Offensive

The new version of Call of Duty is more complex than the earlier one. Although still based on the Quake 3 engine, it is now more visually attractive. United Offensive isn’t strict with the graphics card – all the top-end devices have a speed of over 150 frames per second in it.

You shouldn’t take the results of the two first resolutions seriously as they are obviously limited by the performance of the system’s central processor. This level of this limit differs between ATI’s and NVIDIA’s cards, which is indicative of the difference in their OpenGL drivers. The graphics subsystem becomes the bottleneck in 1600x1200 only, and the GeForce 6800 GT, the RADEON X800 XT and the newcomer, the X850 XT Platinum Edition, have almost the same speeds there.

With enabled full-screen antialiasing and anisotropic filtering we have a different picture – ATI’s graphics cards win the resolutions above 1024x768, but they have always been good in such hard operational modes! There’s a difference of 10fps between the two top RADEONs, although it looks negligible against the absolute speeds of about 120-130fps.
