vs_2_0 - Direct3D Shader Model 2.0 vertex profile for DirectX 9 vs_2_0 This Direct3D profile corresponds to the per-vertex functionality introduced by GeForce FX (NV3x) for DirectX 9. The compiler output for this profile conforms to the textual assembly defined by DirectX 9's Vertex Shader 2.0 shader format. See: http://msdn.microsoft.com/en-us/library/bb172928.aspx Requires Direct3D 9 support. Number of 4-component vector temporaries the target implementation supports. Number of instructions the target implementation supports. Number of draw buffers or Multiple Render Targets (MRT) the target implementation supports. The half data type makes use of the Partial Precision instruction modifier to request less precision. NVIDIA GPUs may use half-precision floating-point when the Partial Precision instruction modifier is specified. Half-precision floating-point is encoded with a sign bit, 10 mantissa bits, and 5 exponent bits (biased by 16), sometimes called s10e5. The float data type corresponds to a floating-point representation with at least 24 bits. NVIDIA GPUs supporting vs_2_0 use standard IEEE 754 single-precision floating-point encoding with a sign bit, 23 mantissa bits, and 8 exponent bits (biased by 128), sometimes called s10e5. Older ATI GPUs use 24-bit floating-point. The fixed data type is treated like half.
