Vertex shader

[rAvEN^Rd]

The GF4 MX boards isn't fitted with a vertex shader right? I do, however, believe that these boards pass the vertex shading tests in 3dMark. Does this mean that it's supported in software instead of hardware? Does the CPU or the GPU pay the price for this?

Every card is able to pass vertex shader test in 3D Mark, because of software fallback. If hardware does not expose vertex shader functionality Direct3D runtime will emulate them in software. GeForce 4 MX does however provide some vertex shader functionality and thus exposes hardware vertex shaders, but still receives software help for unsupported functionality.
