D3D12_CONSERVATIVE_RASTERIZATION_TIER

Identifies the tier level of conservative rasterization.

Syntax

typedef enum D3D12_CONSERVATIVE_RASTERIZATION_TIER
{
    D3D12_CONSERVATIVE_RASTERIZATION_TIER_NOT_SUPPORTED = 0,
    D3D12_CONSERVATIVE_RASTERIZATION_TIER_1 = 1,
    D3D12_CONSERVATIVE_RASTERIZATION_TIER_2 = 2,
    D3D12_CONSERVATIVE_RASTERIZATION_TIER_3 = 3
} D3D12_CONSERVATIVE_RASTERIZATION_TIER

Constants

Constant	Description
D3D12_CONSERVATIVE_RASTERIZATION_TIER_NOT_SUPPORTED	Conservative rasterization is not supported.
D3D12_CONSERVATIVE_RASTERIZATION_TIER_1	Tier 1 enforces a maximum 1/2 pixel uncertainty region and does not support post-snap degenerates. This is good for tiled rendering, a texture atlas, light map generation and sub-pixel shadow maps.
D3D12_CONSERVATIVE_RASTERIZATION_TIER_2	Tier 2 reduces the maximum uncertainty region to 1/256 and requires post-snap degenerates not be culled. This tier is helpful for CPU-based algorithm acceleration (such as voxelization).
D3D12_CONSERVATIVE_RASTERIZATION_TIER_3	Tier 3 maintains a maximum 1/256 uncertainty region and adds support for inner input coverage. Inner input coverage adds the new value `SV_InnerCoverage` to High Level Shading Language (HLSL). This is a 32-bit scalar integer that can be specified on input to a pixel shader, and represents the underestimated conservative rasterization information (that is, whether a pixel is guaranteed-to-be-fully covered). This tier is helpful for occlusion culling.

Remarks
