Call of Duty 4 has to be one of our favourite games of 2007. 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 64-bit version of the game patched to version 1.4. FRAPS is used to record frame rates while we manually walk through a short section of the second level of the game. We find a frame rate 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 4xAA.
The advantage waxes and wanes throughout these tests but there's no doubt the HD 4890 still holds a distinct lead over the GTX 275. Quite simply, this is another round to ATI.
