D3D12_FEATURE_DATA_D3D12_OPTIONS9 structure (d3d12.h)

Indicates whether or not support exists for mesh shaders, values of SV_RenderTargetArrayIndex that are 8 or greater, typed resource 64-bit integer atomics, derivative and derivative-dependent texture sample operations, and the level of support for WaveMMA (wave_matrix) operations.
