Connect to a Running Application (Windows* only)
You may configure Intel® GPA to detect running Windows* application(s), connect to them automatically, and analyze.
Automatic detection may be useful in the following cases:
- When you analyze applications from game platforms (Steam*, Origin*, Epic Games*, and others) and IDEs (Visual Studio*, Unreal Editor*, and others).
- To save time on starting up Intel GPA tools when you launch your application.
NOTE:
Enabled Secure Boot setting blocks auto-detection. Either turn the feature off or consider starting the application directly from the Graphics Monitor (recommended).
Auto-Detect Launched Apps with Graphics Monitor
To enable automatic detection of a running application, do one of the following:
- Press Ctrl and click the Graphics Monitor icon
in the taskbar notification area. - Click the Settings button
in the upper right corner of the Graphics Monitor window and set the Auto-detect Launched Applications setting to ON.
As soon as you turn on automatic detection, the Graphics Monitor icon turns green: 
.
Whenever any application starts, Intel GPA attaches to it and the HUD automatically displays metrics as an overlay on the application window.
Attach to Specific Processes
Once you enable the Auto-detect Launched Applications option, Intel GPA connects to all the processes that use graphics APIs (DirectX*, Vulkan*), including web browsers and non-game applications. To change this, specify the applications that you want/do not want to profile with Intel GPA, once you start them:
- Turn off Automatic detection using Graphics Monitor.
- Go to the Intel GPA installation directory. By default, it is C:\Program Files\IntelSWTools\GPA.
- Add the application names you want to analyze to the InjectionList.txt file or add the application you do not want to analyze to InjectionSkipList.txt. When specifying file names, use the wildcard "*" to replace 0 or more characters, and skip the .exe extension. Example: "my*game", "basichlsl*".
- Save the files.
- In the Graphics Monitor Settings dialog box, turn on Auto-detect Launched Application.
As a result, whenever your application listed in InjectionList.txt starts, Intel GPA gets attached to that process and the HUD is enabled. The tool automatically displays metrics as an overlay on the application window. Applications listed in the InjectionSkipList.txt are not attached to Intel GPA.
NOTE:
If the InjectionList.txt file contains at least one item, the InjectionSkipList.txt file and all other running applications are ignored.
Connect to a Running Steam* App
To run your Steam (or any other supported game platform) application for performance analysis with Intel GPA, do the following:
- Shut down Steam.
- In the Graphics Monitor Settings dialog box, turn on Auto-detect Launched Applications.
- Re-launch Steam.
Alternatively, you can browse to Steam from the Graphics Monitor's Application Executable with Command Line Arguments filed and click Start.
- Run an application from Steam.
