DirectX9.0c Setup included with HL2 CD? HL2 needs DX9.0c?

[Bryan See]

Hey, since HL2 released last November, like the original game did in 1998, HL2 needs DirectX9.0c to run? What happens if HL2 runs on a different DirectX versions (6, 7, 8, 9a or 9b)? In the HL2 CD, there is a DirectX9.0c setup?

They said they will add px 3.0 sooner or later. Plus what you see while playing hl2 isnt no where near the full potentian of the engine. You will need dx 9.0c to see all the effects.

Since HL2 is powered by the Source engine, which supports version 2.0 or below shaders, is HL2 still needs DirectX 9.0c to run?

Yes. 6

What happens if HL2 runs under a different DirectX version like DX9.0a or DX9.0b? I heard that the DirectX9.0c setup is being included on a HL2 installation CD, despite using version 2.0 or below HLSL shaders.
