AMD Radeon HD 6570 512 MB Video Card Review
Call of Duty 4
Contents
Call of Duty 4 is a DirectX 9 game implementing high-dynamic range (HDR) and its own physics engine, which is used to calculate how objects interact. For example, if you shoot, exactly what will happen to the object when the bullet hits it? Will it break? Will it move? Will the bullet bounce back? It gives a more realistic experience to the user.
To get accurate results, we had to disable the 80 FPS limit in the game. To do this, input the command, “/seta com max fps 1000” (minus the quotes) into the console (` key). It can be set to any number greater than 200.
We ran this program at two 16:10 widescreen resolutions, 1440×900 and 1680×1050, maxing out all image quality controls (i.e., everything was set to the maximum values in the Graphics and Texture menus). We used the internal game benchmarking feature, running a demo provided by NVIDIA called “wetwork.” We are putting this demo here for downloading if you want to run your own benchmarks. We ran the demo five times, and the results below are the average number of frames per second (FPS) achieved by each video card.
