Dose directx support 3DNow and SSE ?
DX supports 3DNow, and probably SSE. I know that it DOES support SSE and 3DNow when using Vertex Shaders.
Good Luck

Thank you, but how to make DirectX use it ?
if I only use the HAL initialization will it use the 3DNow ?
or I will init it in another way ?

At some point or another DirectX should detect this capability by itself.

D3D and D3DX do this automatically.
If you are using any of the D3DX Math functions, the first time you call one it will automatically determine SSE or 3DNOW and all subsequant calls will be platform optimized.
You can disable the Processor Specific Graphics Pipeline (PSGP) by adding the entry DisablePSGP (DWORD) to the registry under Direct3D and setting it to one.
