Multiframe Analysis
Graphics Frame Analyzer uses a stream capture file to play back multiple frames, where you can easily play and pause on any frame within your stream to visualize exactly what is happening within your game on a frame-by-frame basis.
A typical framework analysis workflow is as follows:
1.
| To capture a specific stream, you can:
You can share streams with others, to easily recreate areas of interest in an application and isolate frames that highly affect your application. | |
2.
| Load the stream capture file | Launch the Graphics Frame Analyzer to the select the stream capture you want to analyze, or to capture another stream. Once selected, there will be a command line-type icon that shows up in your dock. There is no loading indicator, however, and the application may take a minute to launch. From here, pause and play your stream file to pinpoint relevant frames and isolate performance improvement opportunities. NOTE Playback of the stream files captured with earlier Intel® GPA versions is not supported. Old stream files can be converted to the new stream format at the command line:

3.
| Analyze the captured stream | Explore the performance impact of specific API calls in any frame within the stream, at different stages of the rendering pipeline:
