Call of Duty 4: Modern Warfare

Publisher: Activision

Call of Duty 4: Modern Warfare is different to all previous Call of Duty games, as it moves the action out of the World War II era and into the modern day. We have used the full version of the game with the 1.6 patch applied.

The game runs on a proprietary engine, which includes features like true world dynamic lighting, HDR lighting, dynamic shadowing and depth of field. Unlike most triple-A games that were launched late in 2007, Call of Duty 4: Modern Warfare only uses a DirectX 9.0 renderer and, given the realistic nature of the graphics, it proves that there's still life left in the old dog!

For our gameplay testing, we did a 90 second manual run through in the second mission of the game. All of the in-game settings were set to their maximum values, including texture details which were configured to 'Extra'. The 'Dual Video Cards' option was enabled for the multi-GPU configurations, but was disabled for all single GPU cards.

Finally, anti-aliasing and anisotropic filtering were controlled from inside the game.








The additional 512MB of memory on Gigabyte's Radeon HD 4850 has a small impact on performance in Call of Duty 4: Modern Warfare, but it's not going to change the gaming experience an awful lot. At 2,560 x 1,600 4xAA, you might see some reasonable improvements - 10 percent is nothing to sniff at - but all you'll end up with is a smoother overall experience.
