Syntax

public:
void NopX(
         UINT SizeBytes
)

Remarks

This API is intended primarily for use with Build-Your-Own-Bundles via ExecuteIndirectBundleX. It can be used to align the command buffer data for CPU or GPU efficiency, or to allow embedded meta-data in the command buffer stream that the GPU will ignore. Note that the GPU Command Processor reads the command buffer at 0.5 dwords per clock so it is not entirely ‘free’.

Requirements

Header: Declared in d3d12_x.h.

Library: Use d3d12_x.lib.
