1. What exactly is the CPU test? The graphics seem poorer and much slower.

2. What are the differences between the sound tests? In the first two sound tests are mute...

Thanks....

1: the details / resolution is at the lowest and only the CPU works.

2: 1) no sounds 2) 24 sounds 3) 60 sounds and you can see the difference of FPS between each so you know if your computer / sound cards is doing a good job or not.

Sound test example:

55 fps ( No Sounds )
50 fps ( 24 Sounds )
48 fps ( 60 Sounds )

( this is decent and with a good sound card )

55 fps ( No Sounds )
44 fps ( 24 Sounds )
35 fps ( 60 Sounds )

( this is ... NOT decent and with a bad sound card )

Get it ?

Thank you.

Regardind the CPU test, if resolution/details are at the lowest values possible, shouldn't FPS be high?

Told you .. in this test the video card isnt there to help the CPU ( disabled ) .. the CPU is doing all the job. So you can notice ... video cards are more than important these days.

Actually the video card is doing a lot there but not as much as normally.
Fully software rendering the test would probably take hours.

This test runs game test 1 at a resolution of 640x480 using software vertex shaders. Game test 1 is very
amenable to CPU measurement as the materials used are simple and most of the screen consists of single-textured,
low polygon background objects. We also run game test 3 at a resolution of 640x480 with the use of
dynamic shadows disabled. The optimized code path for 1.4 pixel shaders is disabled, since that feature should
not be credited in this test. Note that this test still depends somewhat on the graphics hardware, but these
settings reduce the dependency.
The CPU test result can also be used as good measure of the software vertex shader speed. Vertex shading is
an important part of 3D game performance. Similar calculations as vertex shading are needed in other parts of
3D game software, such as real-time physics.

It is only vertex shading that are done by the CPU.

Jolly good research sherlock!

Why doesn't it support onboard sound for the sound tests?
