Do I have to modify the software for my game, or install special drivers, in order to be able to use Intel® GPA?
For both the Intel® GPA System Analyzer HUD and the Intel® GPA Frame Analyzer, these tools can analyze your game without any code modifications or special libraries. This is possible because Intel GPA accesses the CPU, driver, DX, and GPU metrics directly from the game environment, a big plus for common analysis tasks. For more complex, task-based analysis with the Intel® GPA Platform Analyzer, you will benefit by inserting API calls that tag the various tasks in your game code — but you’ll just have to do this once, as the ITT API used by Intel® GPA is also used by a number of other Intel performance analysis tools.
