ok! i noe Cg has WPOS under FP30 for GFFX, and HLSL has VPOS under SM3.0 in GF6800, but what about ATI cards that utilise HLSL?? are there any window coord accessing semantics for extended PS2X ?? thx! RC

There is no vPos semantic or register in 2.0 - it is new to 3.0. The same goes for vFace. That means you can't use these features on any ATI cards, as of right now.

ref??? whats that??
"Ref" is the Reference Rasterizer. It is a software rendering device that accurately implements all D3D functionality. However, it's painfully slow (most applications run at 0.5 - 3 fps).

From the SDK:
Quote:
Direct3D supports an additional device type called a reference device or reference rasterizer. Unlike a software device, the reference rasterizer supports every Direct3D feature. Because these features are implemented for accuracy rather than speed and are implemented in software, the results are not very fast. The reference rasterizer does make use of special CPU instructions whenever it can, but it is not intended for retail applications. Use the reference rasterizer only for feature testing or demonstration purposes. To create a reference device, call IDirect3D9::CreateDevice method using D3DDEVTYPE_REF as the device type.
