Firingsquad investigates the performance of Call of Duty 4 with the demo that was released last week.
For this article we’ve gathered the latest high-end GPUs from AMD and NVIDIA, running them through the opening few minutes of the Call of Duty 4 demo. While the game provides a console and supports timedemo mode, this feature appears to be broken at the moment in the demo. We tried both Windows XP and Vista and every time we tried to play back one of our demos in timedemo mode, the game crashed to the desktop.
Instead we used FRAPS to evaluate performance. Now since we’re running FRAPS in an uncontrolled environment where enemies are firing AK47s and RPGs at you and your fellow squad members are firing back at them, we obviously can’t run 100% repeatable runs. We did the best we could, running through the same areas in the same manner, but obviously there are going to be some demo runs where we may take more hits than others, or an RPG may fly right over our head whereas in the previous run it may have exploded in front of us. These are all variables that we can’t control and will obviously affect our performance results, so instead of just taking the average of 3 runs like we’d normally do in a more controlled test, we’re going with seven runs.
