DirectX® 12 Tools (ARCHIVED CONTENT)

GPU PerfStudio now supports DirectX® 12 on Windows 10 PCs. The current tool set for DirectX® 12 differs from the previous generation of graphics  API’s and comprises of an API Trace, a new GPU Trace feature, and a new Object Inspector tool.

  • API Trace – A multi threaded CPU trace of the DirectX® 12 API usage
  • GPU Trace – A new GPU Trace tool for profiling DirectX® 12 CommandLists and analyzing CommandQueue usage
  • Linked Trace – The Linked Trace window supports bidirectional linking between the API and GPU trace windows
  • Object Inspector – Investigate the properties and usage of object instances created by devices

API Trace Window

  • Multi-threaded tracing of the DirectX® 12 API with separate timeline branches for each thread.
  •  Save and Load traces with the new .ATR file format, and Export to .CSV, .TXT, and .XML.
  •  Displays debugging Perf Markers as nested blocks within traced threads through ID3D12GraphicsCommandList’s BeginEvent and EndEvent APIs.
  •  Supports bi-directional navigation with GPU Trace while operating in Linked trace mode.

GPU Trace Window

The GPU Trace window presents profiling information for CommandLists executed on the GPU.

  • View GPU Time for individual commands executed through calls to ID3D12CommandQueue::ExecuteCommandLists.
  • Displays a timeline branch for each CommandQueue used by the connected application.
  • Displays GPU commands within a subbranch of the CommandQueue used to execute CommandLists.
  • View timing data for Draws, Dispatches, Copies, Executes, Resolves, and Clears.
  • Supports bi-directional navigation with API Trace while operating in Linked trace mode.

Linked Trace Window

The Linked Trace window supports bidirectional linking between the API and GPU trace windows.

  • Populates the API and GPU Traces with data collected from a single frame.
  • Find associated execution of APIs between processing units.
  • Allows you to find the CPU-side API invocation by double-clicking a GPU Trace timeline item.
  • Allows you to find the GPU-side command execution by double-clicking an API Trace timeline item.

Object Inspector

The Object Inspector allows the developer to investigate the properties and usage of object instances created by devices.

  • Displays a hierarchical tree of DirectX® 12 API objects utilized by a running application.
  • View all creation arguments used in creating API objects.
  • Find usages of specific API objects within API and GPU Traces.
  • Displays active and destroyed object instances.
  • Able to export object creation arguments as XML.
