Heads-Up Display (HUD) UI Reference

This section provides reference on the UI elements of the Heads-Up Display (HUD), which is an overlay provided at the top left of the screen when you launch the application.
HUD displays system and application statistics on application performance using the GPU and CPU performance metrics selected in the Graphics Monitor
dialog box
When you create trace or frame capture files, HUD displays the following information:
Intel GPA Heads-Up Display
System Information
System Information
includes the following information:
  • Device
    - device name
  • Api
    - Microsoft DirectX* version and device driver type
  • Res
    - screen resolution
  • Monitor Scale
  • Frame
    - index number of the current frame
(Frames Per Second) - frame rate, with lowest value shown in red (157) and the highest shown in green (178); the instantaneous value (161) is calculated for one second.
Status messages
Status messages
are displayed when you create trace or stream capture files. Possible messages are the following:
  • Press "CTRL + SHIFT + T" to capture a trace file
  • Stream recording: ON
  • Name of the captured file on disk
  • Error messages (if any)
HUD keyboard shortcuts
HUD default keyboard shortcuts enable Microsoft DirectX* overrides. By using the keyboard-shortcut assignments, you can run a number of experiments to help isolate performance bottlenecks.

Metrics Charts

When you create frame capture files, HUD displays four metrics charts.
For Intel® HD Graphics 3000/2000 and Intel® HD Graphics GPUs, the Heads-Up Display provides several kinds of data:
  • CPU data
  • DirectX* version
  • GPU data:
    • Execution Units
    • Geometry Shader Input-Assembler
    • Main
    • Memory
    • Output-Merger
    • Pixel Shader
    • Rasterizer
    • Texture Sampler
    • Vertex Shader
For non-Intel GPUs and Intel GPUs prior to Intel® HD Graphic, the HUD displays the following data:
  • CPU
  • DirectX* version
Metrics are displayed in the form of sparklines and include the following data:
  • Metrics name
  • Instantaneous values (white)
  • Minimum metrics values (red)
  • Maximum metrics values (green)
The minimum and maximum values reflect the min/max during the last seven seconds.
The HUD may make available only the default set of metrics that it provides on non-Intel GPUs, even when using Intel® HD Graphics, in the following cases:
  • On non-Intel GPUs and on older Intel GPUs such as Intel® GMA 4500/X4500/X4500HD/4500MHD, only the default set of metrics is available
  • The application is using the Microsoft DirectX* 11 API, but is forcing it to use feature level 9. This is also known as DX11-on-9 mode.
  • The application is using the WARP rasterization (Windows* Advanced Rasterization Platform).

HUD Default Keyboard-Shortcut Assignments

Some games might be using a particular keyboard-shortcut combination. If a default keyboard shortcut does not appear to be working with your game, you can assign new keyboard shortcuts. For information on how to assign a different capture keyboard shortcut, refer to Customize Keyboard Shortcuts.
With the keyboard shortcuts you can capture frame and trace files, pause and resume the application, apply override modes, and switch between HUD modes.
Some games and applications trap all keystrokes, so keyboard shortcuts within the Intel® GPA do not work. In this case, to create frame/trace capture files you can:
  • Use
    Capture Frame/Capture Trace
    buttons of the System Analyzer.
  • Use
    tab of the
    dialog box in the Graphics Monitor to automatically create frame/trace capture files when certain conditions occur, for example when FPS is 20.
Depending on your target system, different override modes might be available.

Since the
Null Hardware
override mode blocks all GPU work, the HUD does not update while
Null Hardware
is in effect. Therefore,
Null Hardware
is applied for two seconds and then automatically resets. You will see the display "freeze" while
Null Hardware
is active. The Null Hardware override is only available on computers using Intel® HD Graphics.
On Intel® HD Graphics 3000/2000 and lower, the
Null Hardware
override implementation requires that all GPU work is blocked. As a result, the HUD is "frozen" while
Null Hardware
is active. On Intel GPUs higher than Intel® HD Graphics 3000/2000, this is no longer a requirement and the HUD continues to update while
Null Hardware
is active and you must manually toggle the override off.
