D3D11_INSERT_FENCE_FLAGS Enumeration

Flags to control inserting a fence, such as whether pending commands are flushed before the fence is executed.

Syntax

typedef enum D3D11_INSERT_FENCE_FLAGS
{
    D3D11_INSERT_FENCE_NO_KICKOFF = 0x0001
} D3D11_INSERT_FENCE_FLAGS;

Constants

Constant	Description
D3D11_INSERT_FENCE_NO_KICKOFF	If this flag is set, pending commands are not flushed and the fence is executed immediately. If this flag is not set, pending commands are flushed before the fence is executed.

Remarks

Setting D3D11_INSERT_FENCE_NO_KICKOFF should be done with caution, as improper ordering of fence insertions and fence waits can cause a fence deadlock. Careful use of this flag can reduce kickoffs and consequently increase speed.

These flags are used by the following methods:

ID3D11DeviceContextX::InsertFence
ID3D11ComputeContextX::InsertFence
ID3D11DmaEngineContextX::InsertFence
