System Analyzer HUD Default Keyboard-Shortcut Assignments
The System Analyzer HUD features the ability to enable Microsoft DirectX* overrides. By using the keyboard-shortcut assignments listed below, you can
run a number of experiments
to help isolate performance bottlenecks.
TIP
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
.
With the keyboard shortcuts you can capture frame and trace files, pause and resume the application, apply override modes, and switch between System Analyzer HUD modes.
NOTE
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:
- UseCapture Frame/Capture Tracebuttons of the System Analyzer.
- Set up a trigger 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 System Analyzer 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 GPUs Intel® HD Graphics 3000/2000 and lower, the
Null Hardware
override implementation requires that all GPU work is blocked. As a result, the System Analyzer 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 System Analyzer HUD continues to update while
Null Hardware
is active and you must manually toggle the override off.
