Intel® Graphics Performance Analyzers Knowledge Base

Intel® Graphics Performance Analyzers (Intel® GPA) includes various features that help game developers optimize their game. This article shows how to use the Pixel History and Overdraw modes to analyze "hot spots" within your game or application.

Recently added to Intel GPA are the Frame Advisor and Erg Advisor tools, which sort through your metrics data to quickly pinpoint specific issues within your frame. The tools highlight areas most likely to result in improving the playability of your game.

Game analysis and optimization is critical, and the complexity of modern GPU's makes this task even more difficult. Intel GPA includes two "advisors" that automate the process of identifying the most likely causes of performance issues in a frame.

This article describes a limitation with the Intel® GPA System Analyzer HUD. When analyzing an application you can't change the monitor or change from windowed mode to full screen mode (or vice versa). We provide suggestions for avoiding this limitation.

Intel GPA Frame Analyzer allows the user to save the a render target image to disk for later analysis. In some cases the resulting image is not what you expected. This article describes the issue and various alternatives for getting what you want.

This article describes the behavior of Intel® GPA on netbooks based on Intel® processors and chipsets. Using Intel GPA with the latest graphics drivers now allows you to analyze and optimize your game on these platforms.

When Intel® GPA creates frame capture files, all DX calls your game makes are included in the file, including calls that return errors. This article describes the tool's handling of API errors, and what you need to do when Intel GPA reports them.

Due to insufficient video memory, Intel® GPA applications may fail when creating and/or reading large capture files. If this occurs, check your video memory settings and increase to a minimum of 512MB.
