D3D12_ROOT_DESCRIPTOR_FLAGS

Specifies the volatility of the data referenced by descriptors in a Root Signature 1.1 description, which can enable some driver optimizations.

Syntax

typedef enum D3D12_ROOT_DESCRIPTOR_FLAGS
{
    D3D12_ROOT_DESCRIPTOR_FLAG_NONE = 0,
    D3D12_ROOT_DESCRIPTOR_FLAG_DATA_VOLATILE = 2,
    D3D12_ROOT_DESCRIPTOR_FLAG_DATA_STATIC_WHILE_SET_AT_EXECUTE = 4,
    D3D12_ROOT_DESCRIPTOR_FLAG_DATA_STATIC = 8
} D3D12_ROOT_DESCRIPTOR_FLAGS

Constants

Constant	Description
D3D12_ROOT_DESCRIPTOR_FLAG_NONE	Default assumptions are made for data (for SRV/CBV: DATA_STATIC_WHILE_SET_AT_EXECUTE, and for UAV: DATA_VOLATILE).
D3D12_ROOT_DESCRIPTOR_FLAG_DATA_VOLATILE	Data is volatile. Equivalent to Root Signature Version 1.0.
D3D12_ROOT_DESCRIPTOR_FLAG_DATA_STATIC_WHILE_SET_AT_EXECUTE	Data is static while set at execute.
D3D12_ROOT_DESCRIPTOR_FLAG_DATA_STATIC	Data is static. The best potential for driver optimization.

Remarks

This enum is used by the D3D12_ROOT_DESCRIPTOR1 structure. To specify the volatility of both descriptors and data, refer to D3D12_DESCRIPTOR_RANGE_FLAGS.
