Call of Duty 4 has to be one of our favourite games of last year. It brought the Call of Duty brand bang up to date and proved that first person shooters didn't need to have the best graphics, or the longest game time. It was just eight hours of pure adrenaline rush that constantly kept you on edge.
We test using the 32-bit version of the game patched to version 1.4 FRAPS is used to record framerates while we manually walk through a short section of the second level of the game. We find a framerate of 30fps is quite sufficient because, although the atmosphere is intense, the gameplay is less so - it doesn't hang on quick reactions and high-speed movement.
All in-game settings are set to their maximum and we test with 0xAA and 4xAF. Transparency anti-aliasing is also manually turned on through the driver, though this is obviously only enabled when normal AA is being used in-game.
Even though the HD 4850 is again beaten by the GTX 260, it once again puts in a good performance compared to its price competitors and looks like a decent option. This title does again highlight the huge difference in performance between the standard clocked HD 4870 and HD 4850 and the benefits of overclocking the latter.
