Feature test - 3D Sound Test
3DMark03 features an exciting new addition - a benchmark of your PC performance when running a 3D scene with multiple 3D sound sources. Game test 1 is processed over 3 runs. First with no sound sources at all (as a reference point), then with 24 sound sources and finally with 60 sources. Each source is accurately modelled to incorporate 3-dimensional positioning, Doppler effects, and attenuation. This test uses the FMOD music and sound effects system.

The test result is shown as the average number of frames per second (fps). The interesting measurement in this test is the difference between the reference run without sounds, and the 24 and 60 sound runs. A smaller difference in frames per second is better.

Note: a sound test run will be skipped if there is no hardware support for the amount of 3D sound sources required.
