3DMark03 is a collection of 3D tests. These include a set of four game tests; these are the only tests used to calculate the overall 3DMark03 score. The benchmark also includes a set of CPU, feature, image quality, and sound tests. Each of these tests measures specific 3D-related functionality, but their result is not included in the overall score. They do not fall into the target usage, but are included to allow the user to evaluate these features. The CPU test is a convenient way to measure the performance of the CPU for typical 3D usage. The feature tests isolate the performance of key 3D features primarily relating to shader technologies. The next set of tests is an exciting new addition to 3DMark: the 3D sound tests. These evaluate the impact of 3D sound sources on 3D graphics performance. The software also includes a set of much-improved image quality tools. These provide a powerful way to ensure integrity of the graphics hardware and drivers.
