POWERVR SGX Optimized Render Order

Basic reference of my understandings of how to batch geometry on the POWERVR SGX chip.

Render Target 1

1. Opaque surfaces

No win to sort by depth.

  1. Shader
  2. Texture & Uniforms
  3. Other states

2. Surfaces using discard (Old Alpha Test)

Same sorting as Opaque Surfaces

3. Transparent surfaces

Sort by depth if necessary
Same sorting as Opaque Surfaces
