The shader math precision series from Xenia Edge: vertex shaders compute as the Xbox 360 GPU does, pixel shaders get cheaper.

Vertex shaders compute reciprocals, square roots, exponentials and logarithms bit for bit as the console, and round sums and products toward zero, which fixes z-fighting and exploding geometry.
Only the results that reach a fetch index, an address register, a memory export or a rounding pay for the exact math.
Pixel shaders drop the 21-bit mantissa rounding, so they cost less in every game, and the option that chose its form is gone.

🇧🇷 Em português

A série de precisão da matemática dos shaders do Xenia Edge: os vertex shaders calculam como a GPU do Xbox 360, e os pixel shaders ficam mais baratos.

Os vertex shaders calculam recíprocos, raízes, exponenciais e logaritmos bit a bit como o console, e arredondam somas e produtos para zero, o que corrige z-fighting e geometria explodindo.
Só os resultados que chegam a um índice de fetch, ao registrador de endereço, a um memexport ou a um arredondamento pagam a matemática exata.
Os pixel shaders deixam de arredondar a mantissa para 21 bits, o que os deixa mais baratos em todo jogo, e a opção que escolhia a forma desse arredondamento sai.
