I have tried out the latest DirectX 9.0c on the GeForce 6800 Ultra card but apparently Shader Model 3.0 has not been implemented yet as evident from the DXCaps Viewer



Here are some performance comparison between the DX 9.0b and DX9.0c :

3DMark2001SE : DX9.0b



3DMark2001SE : DX9.0c



3DMark2003 : DX9.0b



3DMark2003 : DX9.0c



Aquamark3 : DX9.0b



Aquamark3 : DX9.0c



Conclusion :

No performance boost on the 3DMark2003 but a little for the 3DMark2001SE and Aquamark 3.

cool! i'm still on 9.0a :p

So far I checked there is only DX9.0b at MS's DX webby. Where can get DX9.0c? Is it a Beta version?

Due to be realeased with XP service pack 2
Those doing beta tests will already have it.

in my opinion it does not matter too much. perhaps future games that stress on pixel shader 3.0 will have more effects though.

Quite obviously it doesn't give any performance boost on X800XT either.

Did you use SP2 or the 'ripped' DX9.0c zip? If the zip I guess you installed it in safe mode.

maybe offtopic
but 01 scores looks a bit low to me...
i have more on my 3200+ a64 , r9800pro at stock speeds....

fuqqa, 2001 is all about system bandwidth/CPU power - A64 obviously outperforms 3.2C.

example:
On my 3.5G P4 rig X800XT scores around 22k at default clock - on 2.3GHz A64 it scores nearly 28k at default clock
