Description

This section shows the application's CPU-side activity.

The top pane shows rows of active CPU threads, and all of the API calls issued by each thread. Hovering over each call will bring up a tooltip with timing information. This pane may also be easily moved left/right, by holding down the left mouse button on it and dragging left/right. It may also be zoomed in and out using the mouse wheel.

The bottom pane shows one tab per CPU thread, with each tab containing a list of all API calls issued by that thread. Here one can also find function parameters and return results for each API call.

Users may also double click on API calls on either pane, to go highlight the call on the opposite pane.

Once open, timing data may be refreshed by pressing the API Trace button multiple times.
