API Reference > frontend-devtools > Widgets > TileMemoryBreakdown TileMemoryBreakdown Class Beta Breaks down the GPU memory allocated to tiles into categories displayed in two panes. The left-hand pane obtains its information from TileAdmin, displaying the number of selected and unselected tiles that are consuming graphics memory along with the amount of memory consumed. The right-hand pane computes its information from the set of all TileTrees, broken down into groups: "Selected" - tiles that have been selected for display in at least one viewport. "Ancestors" - tiles not selected for display, but have descendents selected for display. "Descendants" - tiles not selected for display, but have ancestors selected for display. "Orphans" - tiles not selected for display that have no ancestors nor descendants selected for display. "Total" - totals of the above categories. Each row of data shows (number of tiles) Group Name: amount of memory consumed by group. The number of tiles in each group includes only those tiles that are consuming a non-zero amount of GPU memory. The widget includes a checkbox to toggle tracking and display of these statistics.
