- There are 12 pixel-shader temporary registers: r0 to r11.
- These registers are used for storing intermediate results during computations.
- If a temporary register uses components that are not defined in previous code, shader validation will fail.
- These are at least floating-point precision.
- A maximum of three can be used in a single instruction.
