CPU Tests:::…

The CPU tests use the regular tests scaled down in resolution, using software vertex processing and disabled post processing. This decreases the graphical workload and increases the CPU workload.
There are 2 CPU tests.
The first test also uses a smart algorithm to calculate the path of the airship in the Canyon Flight test
The second will test the return to proxycon the same way, except it doesn't calculate the AI for it.

Feature Tests:::…

The feature tests do not impact on the overall 3DMark score, but can contain valuable information.

Fill rate Tests
These tests have been included since 3DMark 2000.
They haven't changed much over all the releases.
There are 2 tests single and multi texturing.

Single-Texturing
64 screen size quads are single textured by a 2x2 map.
This is basically the same test as in 3DMark03, except for the smaller texture to reduce bandwidth influence. This test uses the DirectX fixed function rendering path.

Multi-Texturing
8 screen size quads are mapped with 8 additively blended textures.
The maximum amount of fixed function texture layers rendered in a single path is 8, otherwise there could have been more textures per object.
This is also basically the same test as in 3DMark03, except with only a 2x2 texture.
DirectX 9 hardware should support in addition to PS 2.0 also the capability to render 8 texture layers per pass.
We therefore don't need the functionality that 3DMark03 had, where quad texture cards for example rendered 16 objects with four texture layers each.
