Call of Duty 4: Modern Warfare is a first-person shooter developed by Infinity Ward and published by Activision for Xbox 360 , Playstation 3 and PC. It is the fourth installment in the Call of Duty video game series. It was announced on April 25, 2007 and was released on November 6, 2007 in North America. The single player game can be completed in well under seven hours, but the graphics are awesome.

Call of Duty 4: Modern Warfare runs on a proprietary graphics engine, and has features such as true world-dynamic lighting, HDR lighting effects, dynamic shadows and depth-of-field. “Bullet Penetration” is calculated by the engine, taking into account things such as surface type and entity thickness. Certain objects, such as cars, and some buildings are destructible. This makes distinguishing cover from concealment important, as meager protection such as wooden fences, thin walls and such no longer provide sufficient protection. The bullet’s speed and stopping power are decreased after penetrating an object, and this decrease is calculated realistically depending on the thickness and surface of the object penetrated. The game also makes use of a physics engine, which was not implemented in previous Call of Duty titles for the PC. Death Animations are a combination of pre-set animations and ragdoll physics. Some mistook the game’s graphics to be DirectX 10 based, but it is stated that the graphics use DirectX 9.
Results: This article is the first time I’ve included Call of Duty 4 as a benchmark and the results are from a single player level from the game. I dropped a few of the older video games from the charts, but all the latest are still included. The Radeon HD 3870 is below 30FPS at 1280×1024, but remember 4x AA is turned on. CrossFire more than doubled performance on both the Radeon HD 3850 and Radeon HD 3870, which shouldn’t be possbile. The test was run multiple times and the results were the same using three different ATI drivers (7.11 beta, 7.11 official and 7.11 Crysis Hotfix) so I included them in the charts.
Results: At 1920×1200 with 4xAA enabled the Radeon HD 3870 is below 30FPS, but remember 4x AA is turned on. The card started to show signs of fatigue in outdoor environments, but for the most part it did well at 1920×1200. When a pair of Radeon HD 3870 graphics cards was used in CrossFire the performance at 1920×1200 with 4xAA (the highest possible setting in the game menu) was great and more than playable.
