The API Log tab displays the API calls for selected ergs made by the application in drawing the frame.
The data is organized in a tree structure, with the top levels representing the same ergs as shown in the bar chart and the Scene Overview pane. Second-level items represent all the API calls associated with the erg.
If there were any errors detected by the Graphics Frame Analyzer (such as an invalid parameter to a draw call), they will be highlighted in red in this window.
The information in this tab is read-only.
Right-click on an erg node and chose Select Ergs from the context menu. Ergs will be highlighted in the Visualization pane.
