  D3DWDDM1_3DDI_TRIM_MEMORY
} ;

Constants

 
D3D11_1DDI_FLUSH_UNLESS_NO_COMMANDS
The driver should not submit command buffers if there have been no new commands since the last time the driver submitted a command buffer.
D3DWDDM1_3DDI_TRIM_MEMORY
The driver should free as much memory as it can. However, it should not free any memory that the driver requires to continue operating. Using this constant value therefore should not introduce new opportunities to run out of memory.

The driver must no longer call Video memory offer and reclaim DDIs on the memory that it frees.
