Microsoft DirectX 9.0

Vertex Shader 2_0

A programmable vertex shader is made up of a set of instructions that operate on vertex data. Registers transfer data in and out of the ALU. Additional control can be applied to modify the instruction, the results, or what data gets written out.

Instruction Count

Shaders have restrictions for maximum instruction counts.

Each vertex shader can have up to 256 instructions stored.
